PROBLEM TO BE SOLVED: To provide a resin laminated wiper which can prevent a liquid chemical or the like from leaking out to the opposite face of a wiper, can securely hold the wiper, is low cost and compact, and is excellent in a liquid absorptive property. SOLUTION: The wiper is equipped with a liquid absorptive layer 2 made of a liquid absorptive paper or unwoven fabric having protrusions 2a made by embossing on one face, and a liquid impermeable, anti-slip resin layer 4 which is laminated on one surface of the liquid absorptive layer and has a surface 4a following the protrusions. The coefficient of static friction of the resin layer surface measured according to JIS P8147 is 0.7 or higher. Through holes 2x are formed on the liquid absorptive layer near the protrusions by slipping during embossing. COPYRIGHT: (C)2009,JPO&INPIT
