Abstract
A pressure sensor includes a case, terminals, a pressure sensing element, a port, and a temperature sensing element. The terminals are assembled to the case by insert molding and connectable to an external device. The pressure sensing element is electrically connected with the terminals and housed in the case. The port having a pressure receiving hole through which a pressure transmitting medium is led to the pressure sensing element is connected with the case. The temperature sensing element is electrically connected with the terminals and arranged in the pressure receiving hole. A part of each terminal is passed through the pressure receiving hole and extended to the temperature sensing element. The extended part is electrically connected to the temperature sensing element. The extending portion is formed as an insert molding portion of the case and held with a material forming the case.
