PROBLEM TO BE SOLVED: To provide an illumination device improved in air permeability and efficiency of light irradiation to a plant.SOLUTION: An illumination device 100 guides light emitted from a light source by a light guide member and emits the light from a light emission surface of the light guide member so that an irradiation body in an irradiation body region is irradiated with the light. The light guide member has a shape that is bent to form the irradiation body region, at least a part of the light emission surface is provided to be disposed above the irradiation body region, and the light guide member is provided with an opening on a bending surface. |
