PURPOSE: To minimize the number (of filters) of holes for resonance (resonating element) of a band-pass filter(BPF) and to reduce the passing loss and power consumption by coupling the BPF and a specific band rejection filter in one body and thus constituting a filter which has an attenuation band outside a passing band.

CONSTITUTION: Plural holes 12, 13, 14, 15, and 16 for resonance are arrayed and formed in the 1st dielectric block 11 at specific intervals, internal conductor films 12a, 13a, 14a, 15a, and 16a are formed on the internal surfaces of the holes 12∼16 for resonance, and an external conductor film 11b is formed on the other surface of the 1st block 11 except one surface including the openings of the resonance holes 12∼16 to form the BPF 10 having a resonance frequency based on the length of the resonance holes 12∼16. Then, resonance holes 22, 23, and 24 are formed in the 2nd dielectric block 21 and similar conductive films are formed to obtain the BRP 20 which attenuates at least one specific band of attenuation bands of the band-pass filter 10 further partially on the basis of the length of the respective resonance holes 22∼24.
