A substrate for mounting an electronic component according to an aspect of an embodiment includes a base that is a plate-shaped body, where a first surface of the base is sloped relative to a second surface that is opposed to the first surface, and when the base is bisected into a lower part and a higher part in a slope direction thereof, a thermal conductivity of the lower part is higher than a thermal conductivity of the higher part.

Substrate for mounting an electronic component, electrical device, and light-emitting device

A wiring board includes: a base material including, on one side of the base material, a protruding part that protrudes toward an outside, wherein the protruding part has a shape in which a center portion of a principal surface rises from the outer periphery, and a plurality of external connection terminals is arranged on the principal surface. A composite substrate includes: the above-mentioned wiring board and a metallic frame member, wherein the frame member includes an opening whose shape is corresponding to a shape in a plan view of the protruding part, and the frame member is arranged such that the opening surrounds the protruding part to fill a periphery of the protruding part. An electric device includes: an electric element on a right face of the wiring board.

Wiring board, composite substrate, and electric device

A lighting device for a vehicle includes a lighting device body that has a light source part and a housing body that supports the light source part, and a ventilation part-adjacent to the lighting device body and through which outside wind passes. The light source part has a light source element part that emits light and a heat release member that releases heat that is generated in the light source element part. The light source element part is inside of the housing body and the heat release member is exposed inside of the ventilation part.

Lighting device for a vehicle and vehicle

A light-emitting-element housing member includes: a bottom base material having a first surface, and a mounting part on the first surface on which a light emitting element is to be mounted; and a frame member that includes side walls erected on the first surface to surround the mounting part, and an opening that penetrates through one of the side walls. The opening includes an inner edge having a first side and a second side, the first side extends along the first surface and is arranged at a position close to the bottom base material, and the second side extends along the first surface and is arranged at a position far from the bottom base material, and the second side is longer than the first side. An array of the plurality of light-emitting-element housing members, and a light emitting device are also described.
