A panel is disclosed for use in double floors, a number of attachment holes are formed in the rear surface of the panel main body. The leg parts fit into these attachment holes in a state in which a step on the outer circumference of a leg part faces the panel main body. An elastic ring is placed between the step of a leg part and the panel main body. Projections, which are deformed when a leg part is inserted into an attachment hole of the panel main body and which fill the gap between the outer circumference of the leg part and the inner surface of the attachment hole, are formed on the outer circumference of the leg parts.
