PURPOSE:To hold a crystal piece securely by pressing conductive lead pieces which are arranged between vapor-deposited electrodes and a couple of lead wires of an oscillator body by lead-wire connection parts. CONSTITUTION:The vapor-deposited electrodes 5a and 5b having cut parts are formed on both surfaces of a crystal piece 6. Those are clamped by the conductive rubber pieces 7a and 7b having groove parts 11, and the rubber pieces 7a and 7b are arranged inside of a case 3 having projection parts 8a and 8b on the bottom surface. The case 3 and a base 2 are sealed by a sealing part 9 so that lead wire connection parts 10 of lead wires 4a and 4b arranged piercing the base 2 are pressed against upon the conductive rubber pieces 7a and 7b. |
