A combustion pressure sensor (1) for detecting a pressure in the combustion chamber (61) of an internal combustion engine includes a heat releasing member (5) disposed between a housing (2) and a pressure transmitting member (3) at a position forward of a load detecting section and slidable relative to the pressure transmitting member for releasing heat through heat transfer from combustion gas, which has entered an axial hole of the housing from the combustion chamber, to the housing.
