PROBLEM TO BE SOLVED: To attain a wide light distribution angle in a lighting device.SOLUTION: A lighting device 100 includes: a light emission part 121 formed by semiconductor light emitting elements; and a cover member 103 covering the light emission part 121. The lighting device 100 includes a half reflection member which is attached to the cover member 103 so as to protrude from the cover member 103 to the light emission part 121 side, transmits part of light emitted from the light emission part 121 to the cover member 103, and reflects the other of the light to the light emission part 121 side.SELECTED DRAWING: Figure 1 【課題】照明装置において広い配光角を得る。【解決手段】照明装置１００は、半導体発光素子からなる発光部１２１と、発光部１２１を覆うカバー部材１０３とを備え、カバー部材１０３から発光部１２１側に向かって突出するようにカバー部材１０３に取り付けられ、発光部１２１からカバー部材１０３に向かって放射される光の一部を透過させ、残りを発光部１２１側に向かって反射させる半反射部材を備える。【選択図】図１
