A light-emitting device, including: a pair of light-transmissive insulator sheets each provided with a light-transmissive electroconductive layer, or a pair of alight-transmissive insulator sheet equipped with light-transmissive electroconductive
layers and alight-transmissive insulter sheet free from a light-transmissive electroconductive layer, disposed opposite to each other so as to form a region between the pair; at least one light-emitting
semiconductor element each provided with a
cathode and an
anode which are individually and electrically connected to one of the light-transmissive electroconductive
layers, and a light-transmissive
elastomer, disposed between the pair of light-transmissive insulator sheets so as to fill the region in combination; wherein the light-transmissive
elastomer is present at least locally between the
cathode and
anode, respectively, of the light-emitting
semiconductor element and the light-transmissive electroconductive
layers, and the light-transmissive
elastomer is also present at concavities of the
cathode and
anode surfaces.
