Abstract

The invention prevents a pressure receiving space of a pressure sensor from being electrically charged. In a pressure sensor, a diaphragm is attached to a base which is fixed within a cover and a pressure receiving space in which an oil is sealed is formed. A semiconductor type pressure detecting device is connected to a plurality of terminal pins by a bonding wire. A neutralization plate attached to a periphery of the semiconductor type pressure detecting device or a part of the periphery thereof is connected to an earth terminal pin by an earth bonding wire, or is connected to the earth terminal pin by a soldering so as to prevent an insulative medium sealed within the pressure receiving space from being electrically charged.
