PROBLEM TO BE SOLVED: To provide a corner draining material in which the drainage is sufficiently performed to a corner part, even if a gradient is a downward flow surface inclined gently or substantially horizontally.SOLUTION: A corner draining material 6 is disposed in a corner part between an end of a roof board 32 serving as a support of a downward flow surface and a roof frame 2 intersecting with the roof board. Then, the corner draining material 6 includes an installation piece part 61 stacked up above the roof board, and a water conduit 62 formed from an edge of a water lower side of the installation piece part toward a lower side. Here, the water conduit includes a floor surface part 623 serving as the downward flow surface, a first side surface part 621 for closing between the floor surface part and the installation piece part, and a second side surface part 622 opposed to the first side surface part across the floor surface part. |
