Abstract

PURPOSE:To decrease the assembly and processing cost and to save the installing space by forming directly a filter part to a part of a circuit board. CONSTITUTION:An interdigital strip line filter part 11 connected to a signal lines 9, 10 is formed to an upper face of the circuit board 8 being a dielectric substance having a high dielectric constant. The filter part 11 consists of guard electrodes 12, 12'. resonance electrode groups 13, 13', and an earth electrode 14 provided to the back side of the circuit board 8, and the guard electrodes 12, 12', and the earth electrode 14 are connected with a conductor material provided to a through-hole 15 of the guard electrodes 12, 12'. A cover board 18 made of the dielectric substance the same type of material as that of the circuit board 8 and provided with an earth electrode 17 from the outer surface over the back side is laminated to the upper part of the filter part 11.
