The light-guiding structure has the hole 50b penetrating the housing 50, the LED 40a which emits light along the inner wall of the housing 50, and the light-guiding member 60. The light-guiding member 60 has the light entrance 61, the light guide 62 which extends along the inner wall of the housing toward the hole 50b from the light entrance 61, the extending part 64 which bends from the light guide 62 and extends to the outside through the hole 50b, the reflecting surface 63 which is formed at the outer corner of the bend between the light guide 62 and the extending part 64, and the light exit 65 which permits the light, which has been guided by the light guide 62, the reflecting surface 63, and the extending part 64, to emerge toward the outside.
