摘要： The invention is a crystal oscillator having a vibrating plate comprising a vibrating part surrounded by a rim part spaced from the vibrating part except for a narrow connecting part that connects the vibrating part to the rim part in a cantilever fashion. The thickness of the vibrating part and the connecting part are less than the thickness of the rim part. The vibrating part is sandwiched between a pair of casings. Each of the casings has a recess facing the vibrating part, which prevent the vibrating part from contacting the casings. Each surface facing a recess has an electrode positioned thereon and an electrode lead extending from the surface electrode to the connecting part. Each casing has a through-hole positioned to face an electrical lead. A cup-shaped metal lead is placed in each through-hole with the bottom of the cup contacting the electrical lead facing the through-hole. Current to the surface electrodes is supplied through the metal leads.
