PROBLEM TO BE SOLVED: To provide a force transducer capable of increasing a rate of change in resistance value to a strain when the resistance value of a strain gauge stuck on a strained portion is adjusted.SOLUTION: A strain gauge is stuck to be positioned at a region where a strain occurring in a strained portion is detected. A plurality of wiring-shaped resistance pattern parts provided in the strain gauge and reciprocated by return have a short circuit wiring part constituted of a plurality of short circuit wirings arranged at a predetermined interval. The extending direction of the strain detection region of the resistance pattern part generated by cutting a short circuit wiring part is coincident with a direction in which the absolute value of strain of the strained portion is reduced. A resistance value is adjusted by sequentially cutting a short circuit wiring at a position having a larger strain absolute value out of the plurality of short circuit wirings.SELECTED DRAWING: Figure 3 |
