検出装置。A ring-shaped pressure sensor is inserted into the mounting surface of the ignition plug that is screwed into the cylinder head, and this pressure sensor is integrated by casting an insulating mold member around the stack of piezoelectric elements and electrodes. In a pressure detection device for an internal combustion engine, which measures the cylinder internal pressure using the output of the pressure sensor, continuous minute irregularities are formed on the outer periphery or inner periphery of the upper and lower electrodes that sandwich the piezoelectric element of the pressure sensor, The pressure detection device is characterized in that the periphery of the unevenness is surrounded by a molded member.
