Abstract
PURPOSE:To make a frequency adjustment easily and also to mass-produce crystal vibrators by integrally forming the vibration part and support part of a crystal vibrator, by fixing the vibrator to a mount member at one point, and then by making a fine frequency adjustment with the vibrator contained in a case. CONSTITUTION:On both top and reverse surfaces of a crystal plate such as a CT- cut or DT-cut plate causing contour-sliding vibration as its basic vibration, metal films of Cr and Au are vapor-deposited, several external patterns are formed at a time by photoetching, and a crystal vibrator shape is formed by chemical etching. This vibrator 31 has its vibration part and support part integrated and its frequency and Q value are never influenced by the length of a support line; and vibrator 31 is fixed on mount member 34 at one point and metal films are vapor-deposited with the vibrator installed in a case, thereby making a fine frequency adjustment. Consequently, the frequency adjustment is simplified and mass-production is realized.
