The substrate includes a plate-like base member and a copper foil layer formed on part of the base member. The substrate includes a first area and a second area. The first area is an area that is provided so as to surround an element mounting area where a semiconductor light-emitting element is mounted thereon when viewed from the top of the substrate and does not include with the copper foil layer. The second area is an area that includes a part provided so as to surround the first area and the element mounting area; and where the copper foil layer formed. The substrate has a white resist layer disposed thereon that covers the first and second areas and is formed thicker on the first area than on the second area.
