SOLUTION: A roof material 1 has the panelized solar battery 2 and the roof material body 3 having a recess 31 for housing the solar battery 2 on its surface, wherein the bottom of the recess 31 comprises supporting parts 36, 37 for supporting the solar battery 2 and concavities 34 arranged lower than the supporting parts 36, 37. On or near the downstream side edge of the roof material body 3, drains leading to the concavities 34 are formed. The supporting parts 36, 37 are separated in plural portions as they are distanced from the entire peripheral edge of the recess 31,and their upper surfaces are on the same level. The concavities 34 include recessed drains 32a extending in the direction of water flow.</p> |
