Abstract

PURPOSE:To increase the frequency aging characteristics, frequency stability and Q value, by avoiding the interference of oscillation, through the provision of a connecting electrode film closely around the bottom of a base where the oscillation of a tuning fork type oscillator is very less. CONSTITUTION:A plane electrode 1 of a left branch crosses with a plane electrode 3 of a right branch in three dimensions via an insulation film 5 made of SiO2 or the like formed with CVD or aputtering and is connected with the side electrode of the right branch. The electrode 2 of the right branch is connected to the side electrode of the left branch through an insulation film 2 the same as the front side, and the plane electrodes of front and back sides are connected by using the bottom surface at the base bottom.
