Abstract
A pressure sensor is composed of a cylindrical connector case firmly connected to a housing and a pressure-detecting chamber formed between the connector case and the housing. The pressure-detecting chamber is confined by a metal diaphragm, an outer peripheral portion of which is firmly held at a portion connecting the connector case and the housing. A relatively thick ring plate is connected to a mounting surface of the housing, and the outer peripheral portion of the metal diaphragm is sandwiched between the ring plate and a pushing plate placed on and connected to the ring plate. Thus, the pressure-detecting chamber containing a sensing element therein is surely sealed even if the housing is made of a material, such as aluminum, which is different from that of the metal diaphragm.
