An insulating side plate having a section is applied to the lead wire portion of the flexible substrate, a polymer piezoelectric film is overlaid on a portion extending from the back electrode portion to the lower end of the insulating side plate, and a protective layer on which an active side electrode is formed is placed on the lower end. The back support, the flexible substrate, and the polymer piezoelectric film are covered with a conductor case whose portion is sealed so that the protective layer overlaps the polymer piezoelectric film via the active surface side electrode. Sonic transducer.
