Abstract

PURPOSE: To realize a crystal resonator excellent in the linearity in the frequency temperature characteristic by selecting optimizingly a cut angle θ of a contour shear crystal resonator.
CONSTITUTION: An exciting electrode 2 is arranged at upper and lower faces of a diaphragm 5 of a crystal 1. The diaphragm 5 of the crystal 1 is connected with a support 3 via a connection part 4 and they are formed incorporatedly by chemical etching. The electrode 2 is formed only to one side of the left side support 3 and the electrode 2 is arranged to the right side support 3 only at the face opposed to the said left support. A board formed by rotating the Y plate by 46∼53° around the X axis is used as the diaphragm 5. Thus, the crystal resonator excellent in the shock resistance and the linearity in the frequency temperature characteristic with small size is realized.
