Abstract

PURPOSE:To efficiently manufacture an ultrasonic wave oscillator which is thin toward broadwise direction of a piezoelectric operating section added with an operation electrode, by laminating high polymer film into multi-layer and cutting off the multi-layered body toward the laminated direction. CONSTITUTION:A film 1 can be provided with piezoelectricity entirely by clipping both sides with polar electrodes in advance, or for the ultrasonic wave oscillation, after forming the electrodes on the entire both sides, the piezoelectricity can be provided through the polarization by using the electrodes. This piezoelectric film 1 is laminated with multi-layered lamination and cut off along cutting lines 2 as shown in dotted lines. The width W of the ultrasonic wave oscillators 4 formed with this cutting is almost coincident with the film thickness of the thickness piezoelectricity in resonance with the same frequency. The ultrasonic wave oscillator 4 forms the ultrasonic wave oscillating plane for the cutting end surface.
