A bathroom floor panel which is securely dried on the next day is provided. When water drops onto a floor panel 1, the surface tension of the water is broken by irregular-shaped portions 8 and the water spreads without forming waterdrops shown by the imaginary line. Also, the irregular-shaped portions 8 reduce the flow velocity of the water so as to prevent the water flowing in channels 7 from being discontinued. With this, although the drain velocity of the water is low, no water remains as an island. Further, even if some water remain on the irregular-shaped portions 8 after the water flows out the channels 7, the water is evaporated in a short period of time bacause the amount of the remaining water is very small. |
