Abstract
A strain generation body and a force sensor equipped with the strain generation body, which can reduce a temperature error between strain sensors and reference resistors and the influence of external noise and which can improve detection accuracy, are provided. A strain generation body comprises a center part, an outer-peripheral part, connecting parts, a plurality of strain sensors, a plurality of reference resistors. The outer-peripheral part surrounds a periphery of the center part. The connecting parts connect the center part and the outer-peripheral part. The strain sensors are provided on main surfaces of the connecting parts. The reference resistors are provided on a main surface of the center part and constitute bridge circuits together with the strain sensors.
