摘要：
An illumination device has a diffusive sheet that diffuses light. The sheet is fitted to a main body 3 of the illumination device by being sandwiched, in the direction of the thickness of the sheet, between the main body 3 and a frame 4 fitted thereto. The sheet has a cut formed in a portion thereof sandwiched between the frame 4 and the main body 3 to prevent bends that develop with a variation in temperature.
