Abstract: A device housing package includes a substrate in a form of a rectangle, having a mounting region of a device at an upper surface thereof; a frame body disposed on the substrate so as to extend along an outer periphery of the mounting region, the frame body having a cutout formed at a part thereof; and an input-output terminal disposed in the cutout. The input-output terminal includes a first insulating layer, a second insulating layer overlaid on the first insulating layer, and a third insulating layer overlaid on the second insulating layer. First terminals set at a predetermined potential are disposed on an upper surface of the first insulating layer. Second terminals set at a predetermined potential are disposed on a lower surface of the first insulating layer. Third terminals through which AC signals flow are disposed on an upper surface of the second insulating layer.

Abstract: A light-emitting device includes a substrate, a pair of electrode layers disposed on the substrate, a light-emitting element disposed between the pair of electrode layers to keep a first space with each of the pair of electrode layers while electrically connecting with each of the pair of electrode layers, and a pair of reflection layers, each extending in overlapping relation from one to the other one of the pair of electrode layers as seen in a transparent plan view. The light-emitting element is disposed between the pair of reflection layers to keep a second space with each of the pair of reflection layers.
