Glued on. Reference numerals 2a and 2b are terminal portions integrally formed with the metal plate 2 and projecting substantially radially from the plane of the metal plate 2. One terminal portion 2a is directly attached to the printed circuit board longer than the other terminal portion 2b. It is a thing. Here, a plurality of terminal portions 2a may be provided in order to increase the strength when attached to a printed circuit board. In addition, a positioning step portion 2 that functions as a positioning member when it is attached to a printed circuit board is provided at the tip of the terminal portion 2a.
c is provided. Reference numeral 3 is an insulator such as plastic, which is attached to the terminal portion 2b by press fitting so as not to come off. Further, the terminal 4 is integrally formed on the insulator 3, and the terminal portion 2 is previously formed on the insulator 3.
A hole for b is provided. On the extension of the terminal 4, there is provided a contact 4a integrally contacted or soldered on the piezoelectric element 1, and on the other extension, a positioning step similar to the positioning step 2c. A part 4b is provided.
