A crimp terminal includes; a crimping portion and a cover covering the conductor portion, the crimping portion is formed in a hollow cylindrical shape in cross section and has a first end portion and a second end portion opposite to the first end portion. The conductor portion is inserted into the first end portion in a longitudinal direction, and the second end is sealed. The second end portion at the opposite side is sealed by welding. The crimping portion, in which the exposed conductor portion is crimped, further includes a locking section locking the exposed conductor portion. A length between the first end portion into which the conductor portion is inserted and a portion, of the locking section, that is the closest to the first end portion is larger than a length of the exposed conductor portion of the insulated wire.

1. A crimp terminal comprising a crimping portion crimp-connecting a conductor portion exposed from an insulated wire including the conductor portion and a cover covering the conductor portion, wherein, the crimping portion is formed in a hollow cylindrical shape in cross section and has a first end portion and a second end portion opposite to the first end portion, the conductor portion is inserted into the first end portion in a longitudinal direction, and the second end portion is sealed,the second end portion at the opposite side is sealed by welding,the crimping portion, in which the exposed conductor portion is crimped, further includes a locking section locking the exposed conductor portion, anda length between the first end portion into which the conductor portion is inserted and a portion, of the locking section, that is the closest to the first end portion is larger than a length of the exposed conductor portion of the insulated wire. 2. The crimp terminal according to claim 1, wherein the crimping portion, into which the exposed conductor portion is inserted, has a guide section, and an inner diameter of the guide section is smaller than an outer diameter of the cover of the insulated wire and larger than an outer diameter of the conductor portion. 3. The crimp terminal according to claim 2, wherein, a difference between the inner diameter formed by the guide section of the crimping portion and the outer diameter of the exposed conductor portion is larger than a difference between an inner diameter of the first end portion of the crimping portion into which the exposed conductor portion is inserted and the outer diameter of the cover of the insulated wire. 4. The crimp terminal according to claim 1, wherein an outer diameter of the exposed conductor portion is smaller than the outer diameter of the cover of the insulated wire, and an inner diameter of the first end portion of the crimping portion into which the exposed conductor portion is inserted is larger than the outer diameter of the cover of the insulated wire. 5. The crimp terminal according to claim 1, wherein the sealed second end portion is sealed by fiber laser welding. 6. The crimp terminal according to claim 1, wherein the conductor portion is made of an aluminum-based material, and the crimping portion is made of a copper-based material. 7. A crimp-connection structural body, comprising: a crimp terminal which comprises a crimping portion crimp-connecting a conductor portion exposed from an insulated wire including the conductor portion and a cover covering the conductor portion, wherein, the crimping portion is formed in a hollow cylindrical shape in cross section and has a first end portion and a second end portion opposite to the first end portion, the conductor portion is inserted into the first end portion in a longitudinal direction, and the second end portion is sealed, the second end portion at the opposite side is sealed by welding, the crimping portion, in which the exposed conductor portion is crimped, further includes a locking section locking the exposed conductor portion, and a length between the first end portion into which the conductor portion is inserted and a portion, of the locking section, that is the closest to the first end portion is larger than a length of the exposed conductor portion of the insulated wire; andthe insulated wire in which the conductor portion is crimp-connected to the crimp terminal. 8. The crimp-connection structural body according to claim 7, configuring a wire harness comprising at least a combination of the crimp terminal and the insulated wire. 9. A method for manufacturing a crimp-connection structural body, comprising: inserting an insulated wire into a crimp terminal which comprises a crimping portion crimp-connecting a conductor portion exposed from the insulated wire including the conductor portion and a cover covering the conductor portion, wherein, the crimping portion is formed in a hollow cylindrical shape in cross section and has a first end portion and a second end portion opposite to the first end portion, the conductor portion is inserted into the first end portion in a longitudinal direction, and the second end portion is sealed, the second end portion at the opposite side is sealed by welding, the crimping portion, in which the exposed conductor portion is crimped, further includes a locking section locking the exposed conductor portion, and a length between the first end portion into which the conductor portion is inserted and a portion, of the locking section, that is the closest to the first end portion is larger than a length of the exposed conductor portion of the insulated wire; andcrimp-connecting the exposed conductor portion of the insulated wire to the crimp terminal.
