to prevent the solar battery module 44 from disconnecting even when force acting in the direction opposite from the butt object is applied by the engagement further since the solar battery module frame body has the connecting portion 42 which connects the solar battery modules 44 which are adjacent to each other through the fixing member 43 the solar battery modules 44 can be disposed in a building further the position of the fixing member 43 can be moved freely with respect to the solar battery module 44 the fixing member 43 can be slid to a position where there is the structure member 32 which supports the roofboard 31 at predetermined intervals and the fixing member 43 can be mounted at that position the fixing member 43 has a shape such that the length of a t shape of the fixing member 3 is adjusted so that the conventional solar battery module 44 can be sandwiched and the fixing member 43 has a connecting portion 42 there is a solar battery module frame body having a hook shaped to be engaged portion 46 at a location corresponding to the height of the engaging portion 45 of the conventional solar battery module 44 below the upper side of the t shaped eaves side the material of the fixing member 43 is an aluminum extrusion material and its color is black further the fixing member 3 may be a fixing member 50 as shown in fig1 with this as shown in fig1 a portion of the fixing member 50 facing the roof is made thin and long in the flowing direction of the roof as compared with the fixing member 3 the solar battery module frame body can be disposed in a building.
