An illumination device (1) includes: an elongated base member (4) that is to be fixed to a ceiling surface (6); and an elongated frame member (2) that has a light source portion (5) and that is attached to the base member (4) such that the light source portion (5) faces a floor surface. Leaf springs (23) are provided on the rear side of the frame member (2) relative to a side, on which the light source portion (5) is provided, and along the longitudinal direction of the frame member (2). The base member (4) is provided with leaf spring bearings (43) each having an opening (431) through which the leaf spring (23) can be inserted. By inserting the leaf spring (23) into the opening (431) in the leaf spring bearing (43), the frame member (2) is biased toward the base member (4), and the frame member (2) is thus attached to the base member (4).
