するガスケツト型圧力センサ。[Claims for Utility Model Registration] A metal shell having a hollow annular main body and a cylindrical cap communicating with the main body, the main body being connected to a core wire of a lead wire inserted into the cap, an annular electrode plate insulated from the metal fitting; an annular piezoelectric ceramic plate superimposed on the annular electrode plate and insulated from the metal shell; and an annular piezoelectric ceramic plate superimposed on the piezoelectric ceramic plate and electrically connected to the metal shell. The piezoelectric composition includes a ring-shaped presser foot and is fitted into the main body, the core wire, an insulating coating covering the outer periphery of the core wire, and a shield metal mesh surrounding the outer periphery of the core wire, the core wire being connected to the ring-shaped electrode plate. In the gasket type pressure sensor, the metal mesh is connected to the base and a lead wire is inserted into the base, the seal between the lead wire and the base is achieved by inserting an insulating coating into the base and inserting an insulating coating into the base. 1. A gasket-type pressure sensor, characterized in that the outer periphery of the gasket is covered with a metal net, a metal pipe is further fitted on the outer periphery, and the metal pipe is tightened.
