Abstract
PURPOSE:To increase the coefficient of electromechanical coupling, by forming electrodes through the vapor deposition of conductive substance to both sides of a piezoelectric element. CONSTITUTION:Electrodes 2, 3, 2', 3' are provided at both sides of piezoelectric elements 1, 1'. A conductive member 4 serving also as a reinforced plate is bonded in both the sides with the sides of the elctrodes 3, 3' of the elments 1, 1'. The free surface of the piezoelectric elements can be made suited without any excess or shortage by forming the electrodes 2, 3, 2', 3' through the vapor deposition of a metal, and the elctrodes can be formed without any glass flit. Thus, higher static capacitance can be obtained and the coefficient of electromagnetic coupling can be increased.
