Abstract:
A pressure sensor 100 is provided with: a diaphragm 2 that is displaced when pressure is applied thereto; a first pressure receiving section 3 that generates strain when pressed by the diaphragm 2; a second pressure receiving section 4, which is pressed, together with the first pressure receiving section 3, by means of the diaphragm 2 when the strain of the first pressure receiving section 3 is equal to a predetermined value or more, and which generates strain; a first strain gage 5 that detects the strain of the first pressure receiving section 3 by being attached to the first pressure receiving section 3; and an amplifier unit 6 that calculates, on the basis of the strain of the first pressure receiving section 3, pressure applied to the diaphragm 2.
