METHOD FOR FORMING ELECTRODE OF CRYSTAL OSCILLATOR AND CRYSTAL OSCILLATOR

摘要

PROBLEM TO BE SOLVED: To provide an electrode forming method for identifying one side of the X-axis direction of a crystal piece and ensuring holding on one side and to provide a crystal oscillator where CI is made small. SOLUTION: In the electrode forming method of a crystal oscillator, excitation electrodes are formed on both main faces of a rectangular crystal piece and lead-out electrodes are extended to both sides of one end part in the X-axis direction in the crystal piece from the excitation electrodes. One side of the X-axis direction in the crystal piece 1 is recognized, the excitation electrodes are formed on both main faces of the crystal piece 1 and the lead-out electrodes are extended to both sides of one end part being one side of the X-axis direction of the crystal piece 1 from the excitation electrodes.
