While mounting the solar cell module according to 2, 3 or 5, the bolt insertion hole of the first fixing member is inserted in the shaft of the first bolt, and the second hole is inserted in the shaft of the second bolt. Each of the bolt insertion holes of the fixing member is fitted, and further, a second elastic spacer having the insertion hole is fitted, and finally,
A nut is screwed into a shaft portion of each of the first and second bolts, and the first and second fixing members are tightened by the nut and the first and second bolts. Item 7. The method for mounting a solar cell module according to Item 7.
