ABSTRACT:
A pressure sensor includes a case having a concave portion, a sensing portion disposed in the concave portion to output an electrical signal proportional to an applied pressure, a circuit portion disposed in the concave portion and connected to the sensing portion and a conductive diaphragm fixed to the case to cover the concave portion. A conductive member surrounds the sensing portion and the circuit portion to provide an electrical shield. The diaphragm is used as a part of the conductive member.
