A bathroom floor panel for use in an airtight and water tight space is configured to be efficiently dried in a few hours under ambient conditions. When water drops onto the floor panel, the surface tension of the water is broken by irregular-shaped portions and the water spreads without forming waterdrops. Also, the irregular-shaped portions reduce the flow velocity of the water due to a gradient of the panel, so as to prevent the water flowing in channels to a drain from being discontinued. With this, although the drain velocity of the water is low, substantially no water remains as isolated drops. Further, even if some water remain on the irregular-shaped portions after the water flows out the channels to the drain, any amount of water remaining in the channels is evaporated in a relatively short period of time because the amount of the remaining water is very small.

To carry out drying of printing ink with the use of Nano sized high-temperature dryness steam. Nano sized high-temperature dryness steam being clustered on Nano oder is generated and jetted to the print side of printed material so that the Nano sized high-temperature dryness steam imparts intramolecular vibrational energy to ink of the print side. Consequently, the Nano sized high-temperature dryness steam being clustered on Nano oder not only passes through fiber pores in the printed material but also collides with the ink of the print side. The Nano sized high-temperature dryness steam having collided with the ink of the print side imparts thermally excited energy as intramolecular vibrational energy to the ink containing polar molecules. The ink is dried by the intramolecular energy.
