PROBLEM TO BE SOLVED: To provide a surface mounting resonator with simple structure of which the thermal impact characteristics are enhanced by absorbing impact, especially, thermal impact. SOLUTION: In this crystal resonator for surface mounting constituted by storing a crystal chip electrically/mechanically connected with a terminal electrode on the inner bottom surface in a case main body formed in the rectangular shape having a mounting terminal on the bottom surface, covering the crystal chip, tightly sealing the crystal oscillator, it is constituted by providing a plate shaped metal plate of copper or a copper alloy, which is more flexible than soldering on the mounting terminal. In addition, the crystal resonator is constituted by forming rustproof film for preventing rust on the surface of the copper or the copper alloy. COPYRIGHT: (C)2004,JPO
