However, the support member 10 can be stacked in the vertical direction Z. And since each solar cell module 3 can be supported by each support member 10 stacked in the vertical direction Z, even when the solar cell modules 3 are stacked in a horizontal state, the solar cell modules stacked on the top. It is possible to prevent the load of 3 from being transmitted to the lower solar cell module 3. Since the solar cell modules 3 can be stacked in a horizontal state, the cost can be reduced by reducing the packing materials and the transportation efficiency can be improved as compared with the case where the solar cell modules 3 are packed one by one. it can. Further, by providing the engaging portion 14 and the recessed portion 15 on the side surface of the base portion 11, a tenon is formed on the upper end surface of the base portion 11, and a position is formed as compared with the case where a void is formed on the lower end surface of the base portion.
