PROBLEM TO BE SOLVED: To provide a dehydrating roll which can suppress the generation of slime, and can reduce the fraction defective of components to be etched when the dehydrating roll is used in the dehydrating process of manufacturing the components to be etched. SOLUTION: The dehydrating roll is used in the dehydrating process of manufacturing the components to be etched, and composed of a polyurethane porous body with a silver-based antibacterial agent therein. Further, the dehydrating roll is used for printed boards to be etched. COPYRIGHT: (C)2008,JPO&INPIT
