PROBLEM TO BE SOLVED: To provide a substrate for mounting light-emitting elements that achieves satisfactory light reflection of a light-emitting element, can prevent the degradation in a resin layer, and is further advantageous in terms of manufacturing costs by coating the resin layer with a ceramic layer for formation, and to provide a method of manufacturing the substrate for mounting light-emitting elements. SOLUTION: The substrate for mounting light-emitting elements incldues: a metal substrate 10; a columnar metal section 14 formed on the metal substrate 10 directly or via a metal layer 12; an insulating resin layer 16 formed around the columnar metal section 14; the ceramic layer 18 formed while covering the upper surface of the insulating resin layer 16; and a power feed pattern 20a formed on an upper surface of the ceramic layer 18. The method of manufacturing the light-emitting element includes a step of laminating a resin material of the insulating resin layer 16 and metal foil having the ceramic layer in one piece on the metal substrate 10 having the columnar metal section 14, for forming a protrusion A on the surface, for removing the protrusion A, for exposing the columnar metal section 14, and for etching the metal foil 19 by a prescribed pattern to expose the ceramic layer 18.

PROBLEM TO BE SOLVED: To provide a method of manufacturing a wiring board in which the suitable wiring board is obtained while production efficiency is improved and curvature that is highly likely to be generated on the wiring board during continuous production is suppressed. SOLUTION: The method of manufacturing the wiring board includes: a continuous process of forming at least an insulating layer on a long-sized metal foil to continuously obtain a primary laminate; a bonding process of obtaining a secondary laminate in such a way that a pair of the primary laminates are bonded in a state the primary laminates are in opposite vertical directions; a wiring layer forming process of obtaining a tertiary laminate having at least wiring layers on both surface sides of the secondary laminate; and a dividing process of obtaining wiring boards by dividing the tertiary laminate.
