PROBLEM TO BE SOLVED: To provide a light emitting device capable of efficiently dissipating heat generated by a light emitting element.SOLUTION: A light emitting device 1 comprises: a board 11 having a heat dissipating via 19 penetrating through from an upper surface to a lower surface thereof; a light reflection layer 21 formed on the board 11 so as to cover a boundary 17 between the board 11 and the heat dissipating via 19; a translucent protective layer 23 formed on the light reflection layer 21; an element mounting plate 25 disposed at a position, where at least a part of the element mounting plate overlaps with an upper region of the boundary 17, so as to be partially buried in the upper part of the protective layer 23, and comprising a material having thermal conductivity higher than that of the protective layer 23; and a light emitting element 13 mounted on the element mounting plate 25. |
