Light emitting device having heat dissipation terminal arranged on substrate

A light emitting device comprising:

• a substrate having a first main surface, a second main surface that is opposite from the first main surface, and a mounting surface that is adjacent to at least the second main surface, the substrate including an insulating base material and a pair of connection terminals;
• a light emitting element mounted on the first main surface of the substrate;
• a sealing member that is in contact with at least a part of a side surface of the light emitting element and is formed substantially in the same plane as the substrate on the mounting surface;
• a light transmissive member that covers an upper surface of the light emitting element and an upper surface of the sealing member;
• and
• a heat dissipation terminal that is arranged generally in the center on the second main surface of the substrate and that has a recess portion as viewed along a direction normal to the second main surface.
