UNIT, ELECTRONIC DEVICE, AND METHOD FOR MANUFACTURING ELECTRONIC DEVICE

摘要

A unit provided with a panel (10), a piezoelectric element (30) fitted to the panel (10), and a substrate (25) fitted to the principle surface of the piezoelectric element (30), the unit being designed to convey a sound as a contact portion of a human body vibrates, the contact portion being in contact with the panel (10) made to deform by the piezoelectric element (30), wherein the substrate (25) has a base material (25a) comprising a resin, and signal wires (25b) and (25c) disposed in layers on the base material (25a) and connected to the principal surface of the piezoelectric element (30), the principal surface of the piezoelectric element (30) being covered substantially completely by the base material (25a).
