  "textContent": "To provide a load sensor hardly causing error in weight measurement even when the environmental temperature of the load sensor varies, portions of a flexible substrate (50), on which strain gauges (54a'-54d') partially composing a sensor (50) are formed, are folded and adhered to the back of the sensor plate (51) with adhesive. Therefore, the strain gauges (54a'-54d') are disposed at portions of the back of the sensor plate (50) corresponding to the strain gauges (54a-54d), respectively. When the sensor plate (51) is subjected to a bending load, a variation in distortion, having a variation amount substantially equal to that undistortion between the strain gauge (54a) and the strain gauge (54c) and having an opposite sign, is generated between the strain gauge (54a') and the strain gauge (54c'). The variation in resistance due to the variation in temperature between the strain gauges (54a,54a') and between the strain gauges (54c,54c') can be canceled by the bridge circuit, resulting in no or little variation in output. An electromagnetic shielding is used with flexible substrate (50). Used with a seat weight measuring apparatus to control seat belt devices and airbag devices.",
