A mount includes a terminal, and a resin portion. The terminal includes a first surface, a second surface, and an end surface having first and second recessed areas that are extend from the first and second surfaces, respectively. The resin portion is integrally formed with the terminal, and at least partially covers the end surface so that the first and second surfaces are at least partially exposed. The resin portion forms a recessed part to accommodate the light emitting device. The second recessed area includes a closest point that is positioned closest to the first surface, and an extension part that extends outward of the closest point and toward the second surface side. The extension part is formed at least on opposing end surfaces of the pair of positive and negative lead terminal. The first recessed area is arranged on the exterior side relative to the closest point.
