PROBLEM TO BE SOLVED: To surely secure conduction between a resonator and a conductive land on a printed board in a laminated piezoelectric filter the thickness of which can be made thinner, the resonator of which is electrically and mechanically protected and which is easily manufactured and assembled. SOLUTION: An elastic conductive paste 20 is formed on the conductive land part 14 of an electrode pattern formed on the top surface of the printed board 3 to be connected with electrodes 8a, 8b of the resonators S, P, the resonators S, P and the printed board 30 are relatively held at a state that the conductive paste 20 is elastically reduced and the conductive land 14 is connected with the electrodes 8a, 8b of the resonators S, P via the conductive paste 20. Thus, the conductive paste 20 is elastically brought into contact with the electrodes 8a, 8b of the resonators S, P by its elastic resilience at the state that the resonators S, P and the printed board 30 are mutually held and electric connection between the conductive paste 20 and the electrodes is secured.
