LOAD SENSOR

To provide a load sensor capable of suppressing the slack of a base member.SOLUTION: A load sensor 1 includes a circuit board 20 that is overlapped on a first region R1 of a first base member 30 where a second base member 50 at one end part in a Y-axis direction is not overlapped, and that is connected to a plurality of conductive wires, an electrode 22 that is disposed on a surface of the circuit board 20 on the first base member 30 side and overlaps with a wiring pattern 33a at a bonding position P1 of the first region R1 on a second region R2 side, connection members 41, 42 connecting the conductive wires to the first base member 30, a connection member 43 connecting the circuit board 20 and the first base member 30 at the bonding position P1, and a connection member 44 connecting the circuit board 20 and the first base member 30 at least near an end part of the first region R1 on the opposite side of the bonding position P1.SELECTED DRAWING: Figure 7 【課題】ベース部材の弛みを抑制可能な荷重センサを提供する。【解決手段】荷重センサ１は、第１ベース部材３０のＹ軸方向の一方の端部の第２ベース部材５０が重ならない第１領域Ｒ１に重ねられ、複数の導体線がそれぞれ接続される回路基板２０と、回路基板２０の第１ベース部材３０側の面に配置され、第１領域Ｒ１の第２領域Ｒ２側の接合位置Ｐ１において配線パターン３３ａに重なる電極２２と、複数の導体線を第１ベース部材３０に接続する接続部材４１、４２と、接合位置Ｐ１において回路基板２０と第１ベース部材３０とを接続する接続部材４３と、少なくとも第１領域Ｒ１の接合位置Ｐ１と反対側の端部付近において回路基板２０と第１ベース部材３０とを接続する接続部材４４と、を備える。【選択図】図７
