PURPOSE:To simplify greatly the manufacturing process by giving the individual division with minute spaces to one of the back and surface electrodes which are provided via the high molecular piezoelectric film. CONSTITUTION:The upper surface of supporter 7 is formed into the concave curve of radius of curvature R in terms of an axial line (a). And back electrode 8 containing a number of slips A1, A2, A3... which are divided with the minute spaces between and vertically to the direction of line (a) substantially; insulators B1, B2, B3... which are to be filled between these slips; high molecular piezoelectric film 9; surface electrode 10; and surface protective film 11 are laminated in that order on the concave. In such constitution, a number of slip-type oscillators are formed with the slips of one of the divided electrode, the other common electrode 10 plus film 9 between the slip and electrode 10. Thus the manufacturing process can be simplified greatly owing to such method in that electrode 8 is formed through division into many parts in the desired form and minutely and then film 9 featuring the piezoelectric property provided previously is adhered merely to electrode 8. |
