A diplexer that can demultiplex and multiplex two signals having wide frequency bands, and a wireless communication module and a wireless communication apparatus using the same, are provided. A diplexer has a multilayer body including a first interlayer, a second interlayer and a third interlayer. On the first interlayer, first resonant electrodes are disposed in an interdigital form. On the second interlayer, a plurality of second resonant electrodes are disposed in an interdigital form. On the third interlayer, there are disposed an input coupling electrode that faces the input-stage first resonant electrode and the input-stage second resonant electrode in an interdigital form, a first output coupling electrode that faces the output-stage first resonant electrode in an interdigital form, and a second output coupling electrode that faces the output-stage second resonant electrode.
