To temporarily moor materials or tools/jigs required for construction to a roof on which disaster preventive tiles are installed when constructing a solar battery module, while suppressing the entry of wind and rain between the disaster preventive tiles and the horizontally long solar battery module installed thereon.

In this constructing method, the horizontally long solar battery module 70 is mounted on the disaster preventive tiles by locking connection fittings 20 to locking protrusions 10 provided on the disaster preventive tiles 1. Short-side frames 74, 75 on the outward side of the solar battery module to be installed most outward of the roof 31 exist on a protruded region 7 between an insertion portion C and a bar portion D of each of the disaster preventive tiles. In this method, the materials or tools/jigs required for construction are temporarily held by hooking hook members 50 on the locking protrusions of the disaster preventive tiles on which the solar battery module is not yet installed.
