Abstract

PURPOSE:To easily manufacture a piezoelectric body with a high resonance frequency, by constituting a the piezoelectric body in such a way that the polarization inversion layer of the piezoelectric body segmented from a rotary X plate of lithium tantalate monocrystal rotated at an angle of rotation of 0+ or -10 deg. around either one side of a Y-axis or a Z-axis is formed a main plane on one side of its confronting main planes. CONSTITUTION:In an oscillator 11, the polarization inversion layer 13 is formed with the depth of 1/2 of the thickness of the piezoelectric body 12 from the main plane 12a on one side of the confronting main planes 12a and 12b of the piezoelectric body 12 segmented from the rotary X plate of lithium tantalate monocrystal rotated at the angle of rotation of 0+ or -10 deg. around at least either one side of Y-axis or the Z-axis, and electrodes 14 and 15 are formed on the main planes 12a and 12b, respectively. In such oscillator 11, polarization Ps' set reversely to polarization Ps from the main plane 12b on the other side, that is, the polarization Ps formed before the polarization inversion layer 13 is formed at the polarization inversion layer 13, and by impressing a high frequency current from a high frequency power source 5 on the electrodes 14 and 15, the resonance frequency is doubled the conventional oscillator in which no polarization inversion layer 13 is formed.
