Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lighting device with good heat-dissipation efficiency since the lighting device conventionally forms a hollow section wherein heat may be accumulated and it is difficult to escape the heat in a structure. SOLUTION: In the lighting device illuminating by making a light-emitting element (LED 2) light-emit, the lighting device has a retaining body (retaining plate 4) for retaining the light-emitting element, and a plurality of heat-dissipation plates 6A-6E arranged on the retaining body and arranged to make the heat-dissipation plates face each other. A through-hole 6A1 penetrating from one heat-dissipation surface to the other heat-dissipation surface is formed in the heat-dissipation plate arranged on one of both ends in the arrangement direction of the plurality of heat-dissipation plates.
