Summary:PROBLEM TO BE SOLVED: To conduct strain measurement for a body with high precision even after a strain gage bonded to the body is replaced. SOLUTION: In this method, a strain 1 of a body grasped at last based on an output voltage (e) of a bridge circuit 16 including a strain gage 1a before replacement, and a strain Δ 2 of the body from the time of the replacement grasped based on the output signal (e) of the circuit 16 including a strain gage 1b after the replacement are used to obtain a value 2 by the operation of an expression: 2= 1+Δ 2.(1+ 1). The value 2 is measured as the strain 2 of the body from the starting time of strain measurement.
