PURPOSE:To prevent a piezoelectric element from contacting with an inner wall of a cylindrical case by fitting diagonally the element in the case, in chip-like piezoelectric oscillation parts containing the element in the case. CONSTITUTION:Terminal caps 31, 32 are provided on both end opening parts of a cylindrical case 2. A recessed part 311 hollowed to the outside of the case 2 is formed on the center part of one terminal cap 31. One end of a piezoelectric element 1 is positioned in the recessed part 311, and thereafter, is connected by soldering, and the other end is connected to a position being eccentric from the center of the cap 32. In this way, the element 1 is fitted diagonally in the case, therefore, it can be prevented that the oscillation part of the element 1 is brought into contact with the inner wall of the case. |
