PROBLEM TO BE SOLVED: To solve the problem of having difficulty in connecting hollow panels with different height (dimension) to each other and taking much time and labor to provide a window or an opening part in a partition composed of the hollow panel although the hollow panel with painting and paper hanger provided on the surfaces of plates fixed to the front and rear of a frame body made of a light alloy and formed in frame shape is used to construct a partition and a booth in temporary facilities for a trade fair, an exhibition, or the like. SOLUTION: The internal wall surface of a side part 2 slightly above a bottom face 5 of a bottom part 3 of a long-sized hollow panel frame body 1 with an approximately U-shaped cross section comprising a pair of side face parts 2, 2 and the bottom part 3, is provided with small projections 6, 6 with a fixed length formed opposedly and intermittently at fixed spaces in a longitudinal direction.
