PROBLEM TO BE SOLVED: To provide a reflection substrate for a light-emitting element, which includes a highly light-reflective layer capable of maintaining gaps at a lower temperature and obtaining strength and adhesion to a substrate without performing high-temperature sintering.SOLUTION: A reflection substrate 30 for a light-emitting element includes an inorganic reflection layer 3 as a light-reflective layer on a valve metal substrate 1. The inorganic reflection layer contains at least one inorganic binder selected from aluminum phosphate, aluminum chloride, and sodium silicate, and inorganic particles having a refractive index of 1.5 to 1.8 inclusive and an average particle diameter of 0.1 to 5 μm inclusive. |
