Abstract:
1. A light emitting unit comprising: a pair of electrode members having high thermal conductivity and low resistance, being substantially rod-shaped and including end surfaces, respectively; an insulating layer integrally interposed only between the pair of electrode members; and a flip-chip-type light emitting device connected to the pair of electrode members in a face-down state and including an anode electrode directly bonded to the end surface of the one electrode member and a cathode electrode directly bonded to the end surface of the other electrode member, and wherein the pair of electrode members and the insulating layer extend in a common longitudinal direction thereof, the light emitting unit is configured to be incorporated in an endoscope insertion portion, and a common longitudinal direction of the lair of electrode members and of the insulating layer is configured to substantially match a longitudinal direction of the endoscope insertion portion; and heat generated in the light emitting device is to be released along the common longitudinal direction of the pair of electrode members and the insulating layer.
