Abstract

PURPOSE:To make easy the support of the oscillator and to increase the Q value, by providing slit in parallel with the lengthwise direction of a rectangular plate. CONSTITUTION:In the crystal thin plate 6 of rectangular size, slits 7, 8 in parallel with the lengthwise direction of a rectangular are provided, the length of branches 9 to 11 are equal each other and the width of the branches 9 and 10 is equal. When the voltage having te frequency equal to the fundamental frequency of the thick slip mode is fed to the meatal thin electrode 12 placed up and dwon surface of th center of th branch 11, the oscillation of thickness slip mode and bending mode is oscillated simultaneously, the oscillation of the thickness slip mode is caused around the electrode 12 of the branch 11, the oscillation of the bending mode is taken place to all the branches 9 to 11, and the oscillation phase of branches 9 and 10 is in phase and the bending mode oscillation phase of branch 11 is opposite to that by branches 9 and 10.
