ABSTRACT:
In a light emitting element module of the present invention, a lens as an optical system for coupling an optical fiber with light emitted from a light emitting element mounted on a substrate is provided for the light emitting element, and the distance between the light emitting element and the lens is defined by a spacer inserted between the substrate and a holder for the lens mounted on the substrate. When this light emitting element module is manufactured, the distance between the light emitting element and the lens is desirably adjusted by properly selecting the thickness of the spacer to be used at that time.
