PROBLEM TO BE SOLVED: To improve a structural characteristic at unfolding time by connecting a panel of the almost half size of a main panel to upper/lower parts of the main panel unfolding in an accordion shape, and unfolding the panel in the direction orthogonal to the unfolding direction of the main panel. SOLUTION: A yoke 4 and a main panel 1 are joined in series by a main hinge 5 from a satellite structure 8 to constitute an unfolding structure 9 of main series. Sub-panels 2, 3 are joined to this main panel 1 by sub-hinges 6, 7 to constitute unfolding structures 10, 11 of sub-series. When lanuching a satellite, these unfolding structures 9, 10, 11 are all folded up to be fixed to the satellite structure 8 by a holding mechanism. The holding mechanism is opened on an orbit, the unfolding structure of the main series is unfolded in the first place, and then, the unfolding structures 10, 11 of the sub-series are unfolded. According to this constitution, the constitution of the two-dimensional unfolding structures 9, 10, 11 can be obtained without using a complicated mechanism.
