Abstract: Infrared radiation device and production method, capable of preventing electrode degradation by heat are provided. Infrared radiation device includes substrate, insulation layer, heat generating layer, electrode, foundation portion and electric conductor. Substrate has cavity exposing part of back surface of insulation layer. Foundation portion exists on inside and outside of vertical projection area (projection direction of which is along thickness direction of insulation layer) of opening edge, on surface of substrate, of cavity. Electric conductor is provided on surface of foundation portion. End of heat generating layer is provided as cover covering electric conductor. Electrode is in contact with surface of covering outside vertical projection area. Conductor has higher melting point than that of electrode and smaller electrical resistance than those of portion and layer.

Abstract: A light source device according to an embodiment is used with a light guide member and a wavelength converting member, and includes a light-emitting element, a light sensor, and a driving unit. The light-emitting element radiates a light beam to be incident on a first end of the light guide member by being supplied with a drive current. The light sensor detects signal light, which has been incident on a second end of the light guide member and transmitted to the first end. The driving unit supplies the drive current to the light-emitting element and controls the drive current based on a result of detection of the signal light.
