There is provided a wiring substrate (1). The wiring substrate includes: a heat sink (10); an insulating layer (20) on the heat sink; first and second wiring patterns (30) on the insulating layer to be separated from each other at a certain interval; a first reflective layer (50) including a first opening (50X) on the insulating layer so as to cover the first and second wiring patterns, wherein a portion of the first and second wiring patterns is exposed from the first opening, and wherein the portion of the first and second wiring patterns is defined as a mounting region (CA) on which a light emitting element is to be mounted; and a second reflective layer (60) on the insulating layer, wherein the second reflective layer is interposed between the first and second wiring patterns. A thickness of the second reflective layer is smaller than that of the first reflective layer. |
