To provide a radio module which enables improvement of efficiency of heat radiation from a feed element to a heat sink and stability of electric connection between an antenna module substrate and a main substrate.SOLUTION: A radio module 1A includes: a main substrate having a first surface and a second surface located at the opposite side of the first surface and formed with a through hole; an antenna module substrate having a third surface electrically connected to the first surface, and a fourth surface located at the opposite side of the third surface and equipped with an antenna; a feed element which is mounted on the third surface so as to overlap with the through hole in a plan view; a heat sink having a base part arranged so as to face the second surface; a heat radiation sheet which comes into contact with both of the feed element and the heat sink; and a fixing mechanism which fixes the heat sink to the main substrate and presses the antenna module substrate to the heat sink.SELECTED DRAWING: Figure 1 【課題】給電素子からヒートシンクへの放熱効率の向上と、アンテナモジュール基板とメイン基板との電気的接続の安定性と、を両立できる無線モジュールを提供する。【解決手段】無線モジュール１Ａは、第１面と、前記第１面とは反対側に位置する第２面と、を有し、貫通孔が形成されたメイン基板と、前記第１面に対して電気的に接続された第３面と、前記第３面とは反対側に位置してアンテナが実装された第４面と、を有するアンテナモジュール基板と、平面視において前記貫通孔と重なるように前記第３面上に実装された給電素子と、前記第２面と対向するように配された基部を有するヒートシンクと、前記給電素子と前記ヒートシンクとの双方に接触する放熱シートと、前記ヒートシンクを前記メイン基板に固定するとともに、前記アンテナモジュール基板を前記ヒートシンクに向けて押し付ける固定機構と、を備える。【選択図】図１
