1. A hitting-electric device comprising:
a hitting-electric plate to which the piezo thin film layer is bonded to one surface while a predetermined thickness is maintained by a predetermined size in a radial direction from a center;
a support guide part provided in an edge area of the hitting-electric plate and supporting the hitting-electric plate; and
a sounding induction surface part interposed between the hitting-electric plate and the support guide part, and tapered so that a cross-sectional thickness decreases from the hitting-electric plate toward the support guide part.
