To provide a method for simply holding a light source to a lighting fixture, which is high in heat dissipation efficiency from a planar light source, in a luminaire for an organic electroluminescent panel using the organic electroluminescent panel as a luminous light source.

In a luminaire for an organic electroluminescent panel in which the organic electroluminescent panel is attached to a lighting fixture, the organic electroluminescent panel is planar and includes a sealing member layer having a metal film on an opposite side (back side) to a light emitting surface. The sealing member layer adheres closely to an attachment surface of the lighting fixture.
