る。In the case of the solar cell module shown in FIGS. 7 and 8, the surface protection member at the peripheral portion of the solar cell module is covered with a frame which can obtain a relatively high dimensional accuracy, and the periphery of the module together with the fixed sealing material. Since it can be sealed, compared to known solar cell modules,
Fixed sealing material (eg room temperature curing type silicone rubber adhesive)
Is not exposed to sunlight or wind and rain to deteriorate, and moisture intrusion into the module does not pose a problem, and the outdoor weather resistance and the holding and fixing property of the module are relatively excellent.

的強度を保持する以上に過大な寸法となる。However, the conventional solar cell modules shown in FIGS. 7 and 8 have the following problems. That is, in FIGS. 7 and 8, the side plate portion 103b of the frame 100b needs to be provided with the screw holes 106 for fixing the adjacent frames 100a, and the screw hole interval must be larger than the diameter dimension of the screw head. . In actuality, in order to obtain a reliable fixing, a space dimension of 3 times or more of the diameter dimension of the screw head is taken, and the W2 dimension and the W1 dimension in FIG. 8 maintain the shape of the frame 100 and the solar cell module. The size is too large to maintain the mechanical strength required to fix and support 200.

量が低下する。Therefore, when the outermost dimensions of the solar cell module 200 are the same, the dimension W3 (FIG. 7) of the main body of the solar cell module is inevitably reduced, which reduces the effective light receiving area of the module. Therefore, the amount of power generation decreases accordingly.

In 100d, the side plates 103b and 103d have a block shape, and since many materials are required, the weight is heavy and the cost is high. Frames 100a, 100
Since c does not need to have screw holes as compared with the side plates 103b and 103d, the width W2 can be made thin, but its end is machined so that it fits in the adjacent frames 100. When the fastening bolt 108 (FIG. 7) is attached to the lower flat plate portion 102, the lower flat plate portion 102 must be processed with respect to the upper flat plate portion 101.
Since the dimension in the width direction becomes large, the machined shape of the end portion becomes complicated, which causes a cost increase.

When making, you have to prepare two types of molds,
This also causes a cost increase, and since the number of parts increases, member management becomes complicated.
