<P>PROBLEM TO BE SOLVED: To provide a band pass filter which provides a coupling factor in a wide range between resonators while keeping low profile characteristics. Ž<P>SOLUTION: The band pass filter 1 has a first resonator 11, a second resonator 21 which is subjected to broadside coupling with the first resonator 11 and a blocking conductor sheet 31 which is disposed in the middle of the first resonator 11 and the second resonator 21 to overlap with a part thereof. In a comb-line arrangement, the blocking conductor sheet 31 is disposed in a position of both short-circuit ends 11a, 21a or both open ends 11b, 21b of the first and second resonators 11, 21, and in an interdigital arrangement, the blocking conductor sheet 31 is disposed in a centerline position of the first and second resonators 11, 21.
