Abstract
A light emitting element unit according to the present invention includes a semiconductor light emitting element that has a surface, a back surface, and a side surface, where the surface or the back surface is a light extracting surface from which light generated inside is emitted, a submount which has a bottom wall and a side wall, has a recess portion defined by the bottom wall and the side wall, and supports the semiconductor light emitting element by the bottom wall in a position in which the light extracting surface is directed upward at the recess portion, and has an inclined surface on the side wall, inclined at a predetermined angle with respect to the bottom wall so as to face the side surface of the semiconductor light emitting element, and a light reflecting film formed on the inclined surface of the submount.
