Abstract
A piezo-electric element includes a piezo-electric element part, a support part, and a stretchable film. The piezo-electric element part includes a piezo-electric film and electrodes between which the piezo-electric film is sandwiched in a thickness direction. The support part supports a peripheral portion of the piezo-electric element part. The stretchable film is provided in an oscillation region located inside of the peripheral portion of the piezo-electric element part. The stretchable film also has a higher elasticity than that of the piezo-electric element part.
