<P>PROBLEM TO BE SOLVED: To provide a leak-proof roof building material having a solar cell function. <P>SOLUTION: Modules 1 having a solar cell panel 5 are laid in an array. A frame 2 extending from eaves along the border of the neighboring modules 1 in the roof width direction orthogonal to the eaves direction supports the lower face-side edges of the modules 1 on the top face. The rainwater flows toward the eaves direction through a U-shaped groove 12 which is defined by the opposing side faces of the modules 1 and the top face of the frame. <P>COPYRIGHT: (C)2013,JPO&INPIT |
