Abstract
A light emitting device includes a package, a cap, a joining member and at least one laser element. The package includes a metal film. The cap includes a light-transmissive member having a lower surface facing the package and an upper surface opposite to the lower surface, and a light blocking film arranged on the lower surface of the light-transmissive member and having a shape defining at least one opening. The joining member joins a part of the light blocking film and the metal film. The at least one laser element is positioned in a space bounded by the cap and the package such that a part of an edge of the at least one opening defined by the light blocking film is disposed directly above the at least one laser element.
