PROBLEM TO BE SOLVED: To provide a pressure-detecting device that can be easily adjusted. SOLUTION: The pressure-detecting device is composed of a pressure sensor 10, a constant-current circuit 20 for supplying current to the pressure sensor 10, and an amplification circuit 30 for amplifying output from the pressure sensor 10. The pressure sensor 10 is electrically disconnected from the constant- current circuit 20. At a part where the pressure sensor 10 is connected to the amplification circuit 30, lands T1 and T2 that can input and output an electric signal are provided.
