<P>PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device for a porous sheet uniformly carrying a coating component over one main surface. <P>SOLUTION: In a porous sheet having one main surface coated with a coating liquid, the other main surface of the porous sheet is contacted with a roll rotating in the opposite direction from a carrying direction of the porous sheet, thereby the one main surface coated uniformly with the coating liquid is formed without the coating liquid staying unevenly on the one main surface of the porous sheet. Then, a solvent is removed from thus manufactured porous sheet having the one main surface coated uniformly with the coating liquid, thereby the porous sheet uniformly carrying the coating component over the one main surface is manufactured. <P>COPYRIGHT: (C)2013,JPO&INPIT |
