1. A light emitter mounting board, comprising:
an insulating substrate comprising an insulating material;
an electrode layer on the insulating substrate, the electrode layer comprising a conductive material;
a resin layer on the electrode layer, the resin layer having a through-hole portion extending in a thickness direction;
a coating layer covering a surface of the resin layer opposite to the electrode layer and covering an inner peripheral surface of the through-hole portion, the coating layer including an in-hole portion covering the inner peripheral surface, the in-hole portion having a lateral thickness gradually increasing from the surface of the resin layer opposite to the electrode layer toward the electrode layer; and
a reflective electrode being recessed and extending at least on a surface of the in-hole portion of the coating layer and on an exposed portion of a surface of the electrode layer, the reflective electrode comprising a reflective conductive material, the reflective electrode having a bottom including a mount area to receive a light emitter.
