Abstract
Provided is a pressure sensor capable of minimizing an influence of heat and accurately detecting a pressure of a high temperature pressure medium. The pressure sensor includes a housing including a tubular tip portion, a pressure measuring part including a piezoelectric substance while being accommodated in the housing, and a diaphragm including a flexible plate-shaped section fixed to an inner side of the tubular tip portion and a rod section interposed between the flexible plate-shaped section and the pressure measuring part, wherein a heat shield plate held on the inner side of the tubular tip portion to shield the diaphragm from a pressure medium is provided. Accordingly, an influence of heat can be minimized, and a pressure of a high temperature pressure medium can be accurately detected.
