PROBLEM TO BE SOLVED: To provide a strain detector with improved productivity capable of easily confirming a communication status between a control logic and a signal processing circuit. SOLUTION: A means is provided, wherein one of commands composed of a write command 55 for writing data to a nonvolatile memory 42 from a signal processing circuit 47 via a first input/output signal line 48, an erase command 61 for erasing the data of the nonvolatile memory 42, and an output command 58 for outputting correction data 57 stored in the nonvolatile memory 42 is received by a control logic 41 in an IC 40a from a signal processing circuit 47, and the means then outputs confirmation data 56, 59, 62 for confirming that one of the three commands is received to the signal processing circuit 47 via the first signal input/output line 48.
