PCT No. PCT/JP94/01477 Sec. 371 Date May 5, 1995 Sec. 102(e) Date May 5, 1995 PCT Filed Sep. 7, 1994 PCT Pub. No. WO95/10861 PCT Pub. Date Apr. 20, 1995A plurality of dielectric sheets are laminated and bonded together to constitute a laminated board. A plurality of strip-shaped resonance electrodes are formed in parallel on a predetermined bonding face of the dielectric sheets, and the strip-shaped resonance electrodes reach opposite edges of the laminated board. Recesses are formed by locally cutting out the portions of the edges of the laminated board in which the respective resonance electrodes are exposed at their particular ends. Grounding electrodes are respectively formed on the obverse and reverse faces of the laminated board, and edge grounding electrodes are formed in the portions of the opposite edges of the laminated board except for the recess.
