PROBLEM TO BE SOLVED: To provide a pressure measuring device capable of adjusting easily an offset voltage of a semiconductor pressure sensor and output sensitivity. SOLUTION: Adjustment of the offset voltage is executed by a variable resistance VR2 installed on the semiconductor pressure sensor, and adjustment of the output sensitivity is executed by providing, on an integration circuit 4, a variable resistance VR1 for adjusting inclination of an integrated waveform outputted from the integration circuit 4, and adjusting the inclination of the integrated waveform by the variable resistance VR1.
