PROBLEM TO BE SOLVED: To provide an axial gap type motor generator which cools a coil without increasing an axial dimension.SOLUTION: In an axial gap type motor generator (76), a rotor (92) and a stator (6) face each other in an axial direction of a rotary shaft (10) of the rotor (92). The stator (6) includes a coil (42), and the rotor (92) includes magnets (50). A case (78) for receiving the rotor (92) and the stator (6) includes a heat radiation member (80), and the heat radiation member (80) contacts with at least one end surface of the coil (42). Preferably, the heat radiation member (80) contacts with an end surface of a winding portion of the coil (42) which is located at the outer peripheral side of the stator (6).SELECTED DRAWING: Figure 13 【課題】軸方向の寸法を大きくすることなく、コイルを冷却できるアキシャルギャップ型電動発電機を提供する。【解決手段】アキシャルギャップ型電動発電機（７６）は、ロータ（９２）の回転軸（１０）の軸方向にロータ（９２）とステータ（６）とが対向している。ステータ（６）はコイル（４２）を含み、ロータ（９２）は磁石（５０）を含む。ロータ（９２）及びステータ（６）を受容するケース（７８）は、放熱部材（８０）を含み、放熱部材（８０）は、コイル（４２）の少なくとも一方の端面に当接する。好ましくは、放熱部材（８０）は、ステータ（６）の外周側におけるコイル（４２）の巻線部分の端面に当接する。【選択図】図１３
