Provided is an optical element which suppresses generation of glare and a dark section and is applicable to planar light emission having improved light efficiency. A light emitting device is also provided. A light emitting device (40) is provided with: a light transmitting member (1) (optical element) having a light inputting section (11) having light inputted thereto, a first light guide section (2) which guides light inputted to the inputting section (11) to a reflecting surface (12), the reflecting surface (12) which is arranged on the first light guide section (2) on the side opposite to the light inputting side and totally reflects light which forms one linear path among inputted light, and a second light guide section (3) which guides reflected light; and a light emitting member (LED (30)) which inputs light to the inputting section (11). The first light guide section (2) contains light scattering particles, which multiply scatter light and generate light that passes through the reflecting surface (12) and is outputted to the external, and the second light guide section (3) partially or entirely outputs inputted light to the same surface to which light passed through the reflecting surface (12) is outputted. |
