Title: Electronic component device
Inventor: YUO RIICHI
IPC: H01L23/02
Filed: 1983-09-06
Abstract: PURPOSE:To improve the adhesion force of a sealing member so as to use this device even under such a severe environment as thermal stress is applied by a method wherein recesses are provided at least at the corners of a square aperture formed in a case in which an electronic component is contained. CONSTITUTION:A piezoelectric resonator 1 is equipped with the case 2, piezoelectric elements 4 contained in this case 2, and terminal plates 6 and 8. All the four corners of the aperture 10 of the case 2 are cut in C-shape, the recesses 12a-12d being formed therein. Besides, the aperture 10 of the case 2 is sealed with the sealing member 14. Therefore, when this piezoelectric resonator 1 is put under the environment of great variations of external temperature, the expansion and contraction of the member 14 in the direction of long side is restricted by the recesses 12a-12d, resulting in the dispersion of its force of expansion and contraction. At the same time, the expansion and contraction of the case itself is partly absorbed by the recesses 12a-12d. Thereby, the thermal stress applied to the member 14 is reduced, and the exfoliation of the member 14 is prevented.
