PURPOSE:To fix a piezoelectric resonator on a board at a position other than the vicinity of electrodes, by surrounding the vicinity of the electrodes on front and rear sides of the piezoelectric resonator with an elastic member and soldering leads of the electrodes on one side to the winding pattern on the board. CONSTITUTION:Elastic members 18, 23 are coated on the front side 9 and the rear side 12 of the piezoelectric plate 8 by printing, for example, to a prescribed thickness. Cream solder is applied to metallic patterns 29, 30 of the board and metallic patterns 21, 22 of the rear side 12 of the piezoelectric plate. Further, the plate 8 is mounted on the board 36 and an upper plate 24 is on the rear side 12 of the plate 8 sequentially. The cream solder is melted through heating for soldering. Then, the lead terminal 20 and the wiring patter 31 are conected with a conductive paste 34. |
