PROBLEM TO BE SOLVED: To provide a steering wheel which enables improvement of heat radiation performance.SOLUTION: A steering wheel has: a ring part core metal 20; a base material covering the ring part core metal 20; and a heat radiation part 43 which is provided at an outer side of an outer surface of the ring part core metal 20, is thermally connected with a light source 42, and is thermally connected with the outer surface of the ring part core metal 20. The heat radiation part 43 is formed by a material having heat conductivity higher than that of the base material and is formed so that its surface area becomes wider than that of the light source 42.SELECTED DRAWING: Figure 8 【課題】放熱性を向上させることのできるステアリングホイールを提供する。【解決手段】ステアリングホイールは、リング部芯金２０と、リング部芯金２０を被覆する基材と、リング部芯金２０の外側面よりも外側に設けられ、光源４２と熱的に接続されるとともに、リング部芯金２０の外側面と熱的に接続された放熱部４３とを有する。放熱部４３は、基材よりも熱伝導率の高い材料からなり、光源４２よりも表面積が広く形成されている。【選択図】図８
