PROBLEM TO BE SOLVED: To provide a semi-coaxial filter and a radio communication module capable of suppressing increase in device size and having a plurality of frequency bands pass.SOLUTION: A semi-coaxial filter 100 according to the present invention comprises: a metallic frame 1; a plurality of first resonators 3 to 5; a plurality of second resonators 6 and 7; a first output antenna 12; and a second output antenna 13. The first resonators 3 to 5 are installed in the metallic frame 1, and resonate at a first resonant frequency. The second resonators 6 and 7 are installed in the metallic frame 1, are approximately orthogonal to the first resonators 3 to 5, and resonate at a second resonant frequency. The first output antenna 13 outputs a first output electromagnetic wave coupled with the first resonator 3. The second output antenna 12 outputs a second output electromagnetic wave coupled with the second resonator 6. |
