Beschreibung
Zusammenfassung:	A light-emitting module substrate of the present invention includes a circuit layer which is formed on one surface of an insulating layer and in which a light-emitting element is mounted, and a metal layer formed of Al or an Al alloy and a heat sink which are laminated in order on the other surface side of the insulating layer. In the heat sink, Cu is present on at least a bonding surface with respect to the metal layer. The metal layer and the heat sink are subjected to solid-phase diffusion bonding on the bonding surface. The thickness of the circuit layer is 0.1 mm or less.
