Claims

[Scope of utility model registration request]

Direct and parallel resonators 1a and 1b and small protrusions 21a' and 21b' that come into contact with the vibration nodes of the resonators.
A plurality of terminal plates 2a and 2b having 2c' and 2d'
, 2c, 2d are laminated and aligned together with an insulating plate 3, and a multi-element type filtering circuit element is housed in a metal case 4 having a terminal leg 41 on the ground side projecting therein. Both the input terminal leg 22a and the output terminal leg 22b, which extend from the terminal plate 2a and the output terminal plate 2b, and whose tips are connected to the external circuit together with the terminal leg 41 of the metal case, are connected to the opening 4a of the metal case. Bend 22a', 22b' so as to abut and sit on the inner end surface 51 of the cover plate 5 of the insulating material to be fitted and sealed, and insert it into the through holes 5a, 5b drilled in the cover plate. A piezoelectric filter characterized in that the insertion part and the fitting part of the lid plate and the opening of the metal case are hermetically sealed with a sealing material 6.
