A space is provided so that the terminal 2. does not come into contact with the vibrating part of the terminal 2.
It has a structure in which the inside of the entire body is protected by resin 6 while taking out the parts 2' and 2''.In order to improve the performance of the parts, two piezoelectric ceramic diaphragms 1°11 are used as in the conventional example. However, as component mounting technology has made remarkable progress, there is a significant demand for miniaturization of piezoelectric ceramic resonators, and the conventional structure cannot meet market demands because they are all mounted on one side of the insulating substrate 3. It was something.
