Abstract

The semiconductor device includes: a base; a first mount placed on the bottom of the base; a second mount placed on the top of the base; a first light-emitting element placed on the bottom of the first mount; and a second light-emitting element placed on the top of the second mount for emitting light. The first light-emitting element and the second light-emitting element are placed so that the emission direction of light from the second light-emitting element is at an angle of depression with respect to the emission direction of light from the first light-emitting element and that the emission direction of light from the first light-emitting element and the emission direction of light from the second light-emitting element substantially coincide with each other as viewed from above the base.
