1. A jack being connected to an electric energy supply or demand part through a lead, comprising:a contact for contacting an outside terminal to be connected to the jack, the contact having a crimping portion for crimping the lead to be connected to the contact, a housing having a contact insertion opening through which the contact is to be inserted and a contact insertion room in which the contact is to be disposed and; a cover for closing the contact insertion opening when the contact is disposed in the contact insertion room; wherein the housing comprises: a crimping portion storage passage for storing the crimping portion and a lead extending part for extending a lead from the crimping portion storage passage to outside of the housing, wherein the contact comprises a hollow pillar-shaped contact being connected to a first lead being crimped at a first crimping portion by crimping, wherein the contact insertion opening comprises a first opening for inserting the hollow pillar-shaped contact, wherein the hollow pillar-shaped contact comprises an L-shaped tongue piece in a vicinity of a base portion toward the first crimping portion of the hollow pillar-shaped contact, wherein the contact insertion room includes a first insertion room for inserting the hollow pillar-shaped contact, wherein the hollow pillar-shaped contact is to be inserted through the first opening into the first insertion room, and wherein the first insertion room comprises: a pillar insertion opening for inserting the hollow pillar-shaped contact along the pillar axis, a first stopping portion for controlling rotation around the pillar axis of the hollow pillar-shaped contact by engaging with the L-shaped tongue piece, in a vicinity of the pillar insertion opening, and a second stopping portion for stopping the hollow pillar-shaped contact at a predetermined position by butting the L-shaped tongue piece as the hollow pillar-shaped contact proceeds into the pillar insertion opening. 2. The jack according to claim 1,wherein the hollow pillar-shaped contact has a pillar connection base portion and an engagement base portion in a vicinity of the base portion toward the first crimping portion of the hollow pillar shaped contact, and wherein the first contact insertion room of the housing includes a third stopping portion for preventing the hollow pillar-shaped contact from falling off the housing by stopping the engagement base portion. 3. The jack according to claim 1,wherein the contact insertion opening is substantially rectangular, wherein the housing has a plurality of sides defining the contact insertion opening, and wherein at least two opposing sides among the plurality of sides have a guide member for having the cover slide with a side end of the cover engaging the guide member to close the contact insertion opening. 4. An electronic device utilizing the jack according to claim 1.5. The jack according to claim 1, wherein the contact comprisesa J-shaped contact having a J-shaped cross section that includes an elastically-bendable front contact connected to a second lead the being crimped at a second crimping portion, and the contact insertion opening includes a second opening to insert the J-shaped contact. 6. The jack according to claim 5,wherein the contact insertion opening is substantially rectangular, wherein the housing has a plurality of sides defining the contact insertion opening, and wherein at least two opposing sides among the plurality of sides have a guide member for having the cover slide with a side end of the cover engaging the guide member to close the contact insertion opening. 7. The jack according to claim 5, wherein the J-shaped contact comprises:a rectangular back plate, a cross section of which constitutes a main part of the J-shaped cross section, a lower bending portion being arranged between the rectangular back plate and the elastically-bendable front contact and providing the elastically-bendable front contact with a spring back force, and right and left guide plates extending frontward from right and left sides of the J-shaped cross section with L-corners; wherein the contact insertion room includes a second insertion room for inserting the J-shaped contact, wherein the J-shaped contact is inserted into the second insertion room through the second opening, and; wherein the second insertion room includes right and left slit openings guiding the right and left guide plates so as to direct the J-shaped contact into the second insertion room. 8. The jack according to claim 7,wherein the J-shaped contact comprises: tip edges positioned at lower ends of the right and left guide plates, and a wedge projection protruding with a wedge slope along a insertion direction into the housing and being arranged on the rectangular back plate being composed of a substantially flat rectangular plate member; wherein the second contact insertion room comprises: a fourth stopping portion for stopping the J-shaped contact to be inserted into the second insertion room by having the tip edges butt the fourth stopping portion, the fourth stopping portion being disposed on an inner wall of the second insertion room, and; a fifth stopping portion being composed of a fragment piece extending from the inner wall of the second insertion room and being to engage with the wedge projection. 9. The jack according to claim 1,wherein the contact comprises: a hollow pillar-shaped contact connected to a first lead being crimped at a first crimping portion, and a J-shaped contact having a J-shaped cross section that includes an elastically-bendable front contact connected to a second lead being crimped at a second crimping portion; wherein the contact insertion opening comprises: a first opening for inserting the hollow pillar-shaped contact therethrough, and a second opening for inserting the J-shaped contact therethrough, and wherein the housing comprises a crimp isolation wall extending toward the contact insertion opening so as to separate the first crimping portion and the second crimping portion, the crimp isolation wall being disposed between the first opening and the second opening. 10. The jack according to claim 9,wherein the contact insertion opening is substantially rectangular, wherein the housing has a plurality of sides defining the contact insertion opening, and wherein at least two opposing sides among the plurality of sides have a guide member for having the cover slide with a side end of the cover engaging the guide member to close the contact insertion opening. 11. An electronic device utilizing the jack according to claim 9.
