Claims

[Scope of utility model registration request]

A plurality of left and right insulating columns are erected on a base made of insulating material, a vibrating element is interposed between these side columns, a longitudinal groove is formed on the lower surface of the element, and input electrodes are placed on the lower surface of both sides. A piezoelectric resonator provided with an output electrode and a ground electrode provided on the upper part of the element, characterized in that the lower part of the periphery of the element is recessed to reduce the contact area between the element and the support. resonator.
