PROBLEM TO BE SOLVED: To provide a composite filter including a high flexibility in structure, a radio communication module employing the same and radio communication device. SOLUTION: In a composite filter, the plurality of coaxial resonator constituting the first band pass filter are each constituted of: a plurality of first through-holes 21a-21f formed on a dielectric substrate 10; and a plurality of sixth through-holes 26 which are arranged around first through-holes and are positioned on an edge of a graphic obtained by combining circles each of which is formed for each of the first through-hole 21a-21f, includes corresponding each first through-hole and includes a predetermined radius centering on the center of corresponding each first through-hole. The plurality of coaxial resonators constituting the second band pass filter are each constituted of a plurality of second through-holes 22a-22f and a plurality of seventh through-holes 27 which are arranged around the plurality of second through-holes and are positioned on an edge of a graphic obtained by combining circles each of which is formed for each of the second through-holes, includes corresponding each second through-hole and has a predetermined radius centering on the center of gravity of corresponding each second through-holes.
