摘要：In a pressure sensor A according to the presenting invention, a piezoelectricelement B formed by a thin film of aluminium nitride is mounted on a base material C ofan insulating material, and output electrodes D and E and output lead wires F and G whichtransmit a signal detected by the piezoelectric element B are mounted on the side of thebase material C. The pressure sensor A is directly mounted on a cylinder head e of aninternal combustion engine, or is mounted on the outer surface of a heater L which issecured at the free end of a glow plug K, whereby it is disposed to face a combustionchamber h. A combustion pressure or oscillations during the operation of the engine canbe detected with a high sensitivity.
