Abstract

PURPOSE:To manufacture a piezoelectric vibrator having high strength and preferable electric characteristics by containing the main ingredient of a piezoelectric porcelain in a glazed baked film of a baked electrode formed on the opposed surface of the porcelain. CONSTITUTION:The internal electrodes formed on the opposed surfaces of at least two piezoelectric porcelains are baked electrodes, and the main igredient of the porcelain is contained in the medicine baked film of the baked electrodes. For instaance, 5wt% of lead zirco titanate powder is added to electrode material paste dispersed in glaze paste with silver and palladium particles, is mixed and dispersed, and an electrode paste is prepared. The piezoelectric material is weighed to form lead zircotitanate as piezoelectric porcelain material, a mixture with organic binder is formed in a sheet shape, is heated and dried, and unbaked piezoelectric sheet is obtained. The electrode paste is coated on the sheet, is then pressurized, is baked, the electrode is baked, the material is sintered, is polarized, and a piezoelectric vibrator is thus formed.
