Beschreibung
Zusammenfassung:	A pressure sensor includes a connection portion provided with a screw portion configured to fix the pressure sensor to a combustion chamber of a vehicle engine; a hollow liquid-enclosing container fixed to one end of the connection portion; a pressure transmission fluid enclosed inside the liquid-enclosing container; a diaphragm fixed to one end of the liquid-enclosing container and elastically deformed when receiving pressure to transmit the pressure to the pressure transmission fluid; a pressure detection element fixed to the other end of the liquid-enclosing container and detecting the pressure transmitted to the pressure transmission fluid and converts the detected pressure into an electric signal; and a heat-dissipating rod provided inside the liquid-enclosing container. The connection portion and the liquid-enclosing container, and the connection portion and the diaphragm are mechanically connected to each other by welding or the like.
