Abstract: A light emitting device includes a substrate, a plurality of light sources, a light reflecting member and a resin member. The substrate defines a through hole. The light reflecting member includes a wall part having a first surface and a second surface. The first surface defines a plurality of surrounding parts respectively surrounding each of the light sources individually or two or more of the light sources in groups. The second surface defines a hollow part. The resin member is disposed inside the hollow part. The hollow part defines a first opening on a substrate side of the wall part. The through hole defines a second opening positioned inner than the first opening. The resin member is continuously in contact with the second surface and the upper surface of the substrate in a region between a peripheral edge of the second opening and a peripheral edge of the first opening.

Abstract: A light emitting device includes a substrate, a plurality of light sources disposed on the substrate, and a plurality of light reflecting members disposed on the substrate. The light reflecting members respectively include wall parts each surrounding each of the light sources individually or two or more of the light sources in groups. Two adjacent ones of the light reflecting members are joined to each other such that outer surfaces of the wall parts of the two adjacent ones of the light reflecting members are bonded to each other via an adhesive agent.
