The present invention provides an electronic pad, including: a struck body, including a first struck portion and a second struck portion; a first and a second vibration sensor, detecting a vibration of the first struck portion and the second struck portion. In the electronic pad, a partitioning portion is interposed between the first struck portion and the second struck portion for partitioning. The partitioning portion includes: a first upright portion, protruding further than at least one of an upper surface of the first struck portion and a lower surface opposite the upper surface; a second upright portion, separated from the first upright portion by a predetermined spacing and protruding further than at least one of an upper surface of the second struck portion and a lower surface opposite the upper surface; and a connection portion connected between the first upright portion and the second upright portion.

The electronic pad according to claim 2, wherein the first struck portion and the second struck portion are formed having a predetermined wall thickness; andat least one of the first upright portion and the second upright portion is formed having a length, extending from the lower surface of the first struck portion and the second struck portion to an inner surface of the connection portion, equal to or greater than the predetermined wall thickness. 4. The electronic pad according to claim 3, wherein the connection portion is formed in an arc shape expanding in an opposite direction from the upper surface of the first struck portion and the second struck portion. 5. The electronic pad according to claim 3, wherein the connection portion is formed in a linear shape in a cross-sectional view. 6. The electronic pad according to claim 1, wherein the first upright portion and the second upright portion protrude further than the lower surface of the first struck portion and the second struck portion; and the connection portion is formed connected between an end portion of the first upright portion toward the upper surface of the first struck portion and an end portion of the second upright portion toward the upper surface of the second struck portion. 7. The electronic pad according to claim 6, wherein the first struck portion and the second struck portion are formed having a predetermined wall thickness; and the connection portion is formed having a wall thickness thinner than the predetermined wall thickness. 8. The electronic pad according to claim 7, wherein an inner surface of the connection portion is formed in an arc shape bending toward the upper surface of the first struck portion and the second struck portion. 9. The electronic pad according to claim 6, wherein a surface of the connection portion toward the upper surface of the first struck portion and the second struck portion is formed continuously flat between the upper surface of the first struck portion and the upper surface of the second struck portion. 10. The electronic pad according to claim 1, wherein the first upright portion and the second upright portion protrude further than the upper surface of the first struck portion and the second struck portion; andthe connection portion is formed connected between an end portion of a part of the first upright portion that protrudes further than the upper surface of the first struck portion and an end portion of a part of the second upright portion that protrudes further than the upper surface of the second struck portion. 11. The electronic pad according to claim 1, wherein the first struck portion and the second struck portion are formed having a predetermined wall thickness; andat least one or more of the first upright portion, the second upright portion and the connection portion are formed thinner than the predetermined wall thickness. 12. The electronic pad according to claim 1, wherein the connection portion is formed thinner than at least one of the first upright portion and the second upright portion. 13. The electronic pad according to claim 1, wherein the first struck portion and the second struck portion are formed having a predetermined wall thickness; andthe partitioning portion forms a groove surrounded by the first upright portion, the second upright portion and the connection portion. 14. The electronic pad according to claim 13, wherein a width of a gap between an inner surface of the first upright portion and an inner surface of the second upright portion of the groove is as long as the predetermined wall thickness. 15. The electronic pad according to claim 13, wherein a length of the groove extending from an opening end of the partitioning portion to an inner surface of the connection portion is twice as long as the predetermined wall thickness. 16. The electronic pad according to claim 1, wherein the partitioning portion is integrally formed with and of the same material as the struck body. 17. The electronic pad according to claim 1, wherein the struck body is formed in a circular shape in a plan view; andthe partitioning portion is formed concentrically with the struck body. 18. The electronic pad according to claim 1, comprising a cover, wherein the cover has higher elasticity than the first struck portion and the second struck portion and covers the upper surface of the first struck portion and the upper surface of the second struck portion. 19. The electronic pad according to claim 1, wherein the struck body is formed in a rectangular shape in a plan view; andthe partitioning portion is formed so that the struck body is partitioned by a vertical frame and a horizontal frame intersecting in a cross shape.
