PROBLEM TO BE SOLVED: To provide a water-eliminating device for a substrate, where the elimination efficiency of water adhering to the front and rear sides of the substrate such as a printed wiring board and the inside of a through-hole is stable. SOLUTION: Upper and lower rollers 1 and 2 that are arranged vertically, are in contact each other by a backup mechanism 4 for collapsing, pass a printed wiring board 8 between them for eliminating water adhering to the surface of the wiring board and a through-hole, and a squeegee for pressing a squeegee 6 to the throwing side of a printed wiring board 8 of the upper and lower rollers 1 and 2 of each roller by an actuator 5 and unloading water which is absorbed by a liquid-absorbing soft material 10 of each roller are provided, at the same time, a cavity 11 is provided inside a roller shaft 3a of each roller, and a drain hole 12 for unloading one portion of water being absorbed by the liquid-absorbing soft material 10 of each roller is provided at the wall, thus preventing the water content of the liquid-absorbing soft material 10 from saturation.
