Abstract

PURPOSE:To obtain easily a high resonance frequency by providing plural adjacent regions different from the direction of polarization and providing an electrode in common to said regions. CONSTITUTION:The polarization direction in the regions 11A, 11B of a piezoelectric ceramic forming body 11 is made opposite as shown in arrows B and C respectively and electrodes 12, 13 are formed in common to the adjacent regions 11A, 11B. Since two-division or three-division structure is adopted in this way, the piezoelectric vibrator having a higher resonance frequency to the piezoelectric ceramic forming body of the same material and size is attained.
