A translucent panel attachment structure according to an embodiment of the present invention includes a translucent panel, a casing, and a silicone resin layer. The casing has an opening into which the translucent panel is fitted. The opening has an inner wall surface which faces a peripheral surface of the translucent panel and an inner bottom surface which inwardly extends from the inner wall surface so as to face a peripheral edge of a back surface of the translucent panel. The silicone resin layer is formed by filling a silicone resin between the peripheral surface of the translucent panel and the inner wall surface of the casing and between the peripheral edge of the back surface of the translucent panel and the inner bottom surface of the casing.
