置。In a pressure detection device for an internal combustion engine, a ring-shaped pressure sensor is inserted into the mounting surface of an ignition plug that is screwed into a cylinder head, and the cylinder internal pressure is measured based on the output of the pressure sensor. A pressure detection device characterized in that the contact surface with the cylinder head is rough, whereas the contact surface with the ignition plug or gasket is dense.
