Claims

[Scope of utility model registration request]

Direct and parallel resonators 1a, 1b and small protrusions 21a', 21b', 2 that come into contact with the vibration nodes of the resonators
A multi-element type filter circuit element in which a plurality of terminal plates 2a to 2d having terminal plates 2a to 2d having terminals c' and 2d' are laminated and aligned together with an insulating plate 3 is housed in a metal case 4 having a terminal leg 41 on the ground side protruding from the metal case 4. The opening 4a of the case is inserted into the terminal board, the input terminal board 2a and the output terminal board 2b.
Airtightly provided by an insulating cover that protrudes from each of the conductive parts 21a and 21b having the above-mentioned small protrusions, and passes through the input terminal leg 22a and the output terminal leg 22b, which are connected to the external circuit together with the terminal leg 41 of the metal case. In the case where the conductive parts 21a and 21b of the input terminal board 2a and the output terminal board 2b are extended toward the open end 4a side of the metal case, their end surfaces 2
An electric filter characterized in that 11a and 211b are brought into contact with the insulating lid.
