Abstract
A pressure sensor according to the present invention comprises a pressure measuring portion which is composed of a resin and contacts fluid, and a sensor element which measures pressure imposed on the pressure measuring portion. Furthermore, a conductive layer having electrical conductivity is provided between the pressure measuring portion and the sensor element, and the conductive layer is connected to a ground. According to this pressure sensor, static electricity accumulated in the pressure measuring portion is released to a ground through the conductive layer without being transmitted to the sensor element.
