A semiconductor light-emitting device of the present invention includes at least one conductor A, that is patterned electrode, 2a, a conductor B, that is patterned electrode, 2b, and a solid-state light-emitting element 3 on one side of an insulating heat dissipating substrate 1. The solid-state light-emitting element 3 is mounted on the conductor A 2a but is not mounted on the conductor B 2b. The solid-state light-emitting element 3 is mounted in such a manner that the whole lower surface that is a surface opposing to a main light extraction surface of the solid-state light-emitting element 3 adheres to the conductor A 2a. When a mounting surface of the solid-state light-emitting element 3 is viewed from above, the conductor A 2a has an element mounting area on which the whole lower surface of the solid-state light-emitting element 3 is mounted and a plurality of outflow-adhesive capturing areas that are provided adjacent to the periphery of the element mounting area without directional bias with respect to the periphery of the element mounting area. The conductor B 2b is disposed in a portion adjacent to the periphery of the element mounting area other than the outflow-adhesive capturing areas while being electrically separated from the conductor A 2a. In this manner, a semiconductor light-emitting device can be provided that can be produced using orthodox practical techniques, can have high output power, can be mounted with high density, and can be designed with consideration given to the case of lighting failures. |
