The substrate for mounting a light-emitting element according to the present invention includes a wire electrode and a resin molded body. The wire electrode has a first main surface, a second main surface opposite to the first main surface, and a cross-sectional view. The resin molded body is continuous with at least a part of the first main surface and at least one of the second main surface, which is continuous with the first concave surface region of the first main surface and one end surface of the second concave surface region continuous with the second main surface And exposing at least a part of the one end surface to be integrally formed with the wire electrode; the second concave surface region includes a closest portion closest to the first main surface and an outer side closer to the first main portion and facing the second main surface The extending portion extending on the surface side, and the first concave surface region is provided outside the closest portion of the second concave surface region. |
