Abstract

PURPOSE:For the quartz crystal oscillator of bar-like thickness shear type, a protrusion which has stage difference in the depth direction is formed at terminal section of oscillator. And this protrusion is held between support materials. As a result, small-size, high-efficiency quartz crystal oscillator for wristwatch use can be obtained with excellent anti-shock property.
