ABSTRACT:
A pressure sensor includes: a housing; an attachment having a pressure input orifice communicating with an interior of the housing; a first diaphragm that seals an opening of the pressure input orifice of the attachment, an external surface of the first diaphragm being a pressure receiving surface; a force transmitting member having an end which is coupled approximately perpendicular to a main surface of the first diaphragm, the main surface being opposite from the pressure receiving surface; a swing arm which is joined to the force transmitting member and is held to a retainer at a pivoting point as a fulcrum; and a pressure sensing element having a first end coupled to the retainer and a second end coupled to the swing arm, so that a displacement direction of the force transmitting member is the same direction as a line joining the first end and the second end. In this pressure sensor, the force transmitting member, the swing arm, the pressure sensing element, and the retainer are housed inside the housing, and the retainer is fixed to an inner wall of the housing.
