Abstract

PURPOSE:To suppress the increase of an equivalent resistance value (C1), by applying a convex working on a rectangular AT vibrator in a prescribed direction, and furthermore, specifying the R of convex. CONSTITUTION:In the rectangular AT vibrator 1, an oblique plane is formed in a direction of X, and the oblique plane is constituted of a circular arc of R1(mm) in the direction of X. Also, in the rectangular AT vibrator 1, the oblique plane is formed in a direction of Z', and the oblique plane is constituted of the circular arc of R2(mm). Also, a holding part 2 is formed at an X direction end part of the rectangular AT vibrator 1. In such a case, relation R1>R2 is set between the R1 and R2. In such a way, since not only the energy confinement of the rectangular AT vibrator 1 in the direction of X but the energy confinement in the direction of Z' can be realized, it is possible to suppress the increase of the value of the C1.
