PROBLEM TO BE SOLVED: To provide a hollow panel made of a synthetic resin repeatedly usable, for example, as an ageing material on a building site or a separate sheet used in the bulk packaging of a drinking water container or the like. SOLUTION: Releasable protective films 2 are laminated on at least one surface of the hollow panel made of the synthetic resin wherein flat sheets 10b, 10c are bonded to both surfaces of an uneven sheet 10a. The protective film 12 is peeled by one at each time of use to always keep appearance like a new article. Further, the hollow panel can be always held to a clean state and the sanitariness thereof can be satisfied. By constituting the hollow panel made of the synthetic resin of a plurality of hollow members 10 made of the synthetic resin connected in a mutually bendable manner, the hollow panel made of the synthetic resin can be arranged to the corner part of a wall or the like without directly forming a slit in the hollow panel to be used as the ageing material.
