The present invention provides a lighting device in which a planar light-emitting panel is supported by, and can be easily attached to and detached from, a support member. The support member has a support side engagement part and covers a large part of a feeding wiring line. The lighting panel has a planar light-emitting panel and a mounting member. The planar light-emitting panel is attachable to the mounting member and has a panel side engagement part on its rear surface. The mounting member is fixable to the support member, and has first and second attaching side engagement parts. The first attaching side engagement part can engage the support side engagement part in a direction substantially orthogonal to the support member at a position overlapping with the planar light-emitting panel. The second attaching side engagement part can engage the panel side engagement part in the orthogonal direction.
