description A mold part formed of a light transmitting material having a high refractive index is molded in a concave-shaped reflecting member, and a light emitting element such as an LED chip or the like is inserted in the center of the mold part. A circular direct emitting portion is provided at the center of a front face of the mold part, a ring-shaped total reflecting portion is provided around it, and a slanted total reflecting portion is provided between the direct emitting portion and total reflecting portion. Thereby, the uniformity of front face luminance with a simple structure in a light emitting device provided with a reflecting member on a back face of a mold part is improved.
