Abstract
PURPOSE:To enable prevention of humming, by covering the outer surface of a piezo-electric film with a metal shield. CONSTITUTION:A piezo-electric type pressure sensor 1 has electrodes 3a and 3b formed on both sides of a high polymer film 2 showing a piezo-electric property, an insulated cord 5 is provided thereon and, moreover, a metal shield 7 thereon. Leads 4a and 4b are mounted on the electrodes 3a and 3b, and a lead 8 on the metal shield 7. This can prevent humming to eliminate the need for a low-pass filter or the like, thereby enabling utilizing of the pressure sensor as such ideally.
