Abstract

PURPOSE:To easily mass-produce piezoelectric oscillators which are strong and rigid, by unifying porcelain through compression and calcination sandwiching electrodes having a number of missing parts between >=2 piezoelectric sheets. CONSTITUTION:An internal electrode 7 having a grating, radiated or concentric shape is formed by printing or coating on a piezoelectric sheet 11 which is not calcined by means of, for example, a screen printing section 12, for example, so that the rate of opening is about 30%. The noncalcined piezoelectric sheets 14 are overlapped, laminated by pressing rollers 1, 13, fed in the direction of an arrow R, and punched out into circular or other desired shapes by a punch 15 to obtain noncalcined piezoelectric oscillators 16. Calcination is made after coating or printing a conductive material on them, to form external electrodes 4, 5, internal electrode leading-out leads and electrodes 6, 7A. Thus, the mass production of mechanically strong piezoelectric oscillators can be made easily.
