Patent abstract

A foil strain gage is attached to a strained section for outputting a resistance change proportional to a strain generated at the strained section. The foil strain gage includes two grid-shaped resistors disposed in parallel on an insulating base material as detecting sections. The two detecting sections generate identical detection outputs when the foil strain gage is bonded on the strained section.
