Abstract

PURPOSE:To reduce the leakage from the supporting part of the oscillation energy and thus decrease the CI value and increase the Q value, by supporting a piezoelectric element that performs a thickness slip oscillation at an area of the outer circumference part. CONSTITUTION:The driving electrode 1a and 1b are formed by the vapor deposition or the like on the main surface of the quartz bar 1. The airtight terminal 2 is sealed by attaching the terminal pins 4 and 5 to the metallic base 3 such as the copper-clad Kovar or the like in an insulated state by the airtight glass 6. The supporting springs 7 and 8 are made of the thin plates of phosphorous bronze, stainless steel and the like and fixed at the upper part of the pins 4 and 5. The supporting parts 7a and 8a above the springs 7 and 8 are opposite to each other having a space equal to the thickness of the outer circumference of the bar 1. Within this space the bar 1 is supported fixedly at an area of the outer circumference part by the conductive paste or the like.
