To improve design of a lighting device. A lighting device includes optically transparent glass plates provided on side faces and placed on an optical path of light emitted from a light source, where some or all of the optically transparent glass plates contain an optically transparent battery adapted to drive the light source; and an optically transparent glass plate that contains a transparent conductive film by being provided on a bottom face, wherein the optically transparent battery is placed in contact with a pair of transparent conductive film layers, which are connected to the light source. The pair of transparent conductive film layers are formed in a pair of parallel linear grooves formed in a surface of the optically transparent glass plate on the bottom face, and a tabular positive tab and negative tab of the optically transparent battery fit in respective ones of the pair of grooves.
