Abstract
A functional sheet is described, in which a modifier is uniformly and exactly scattered and deposited such that sites where the modifier is deposited and sites where no modifier is deposited are clearly discriminated. The functional sheet is obtained by masking a surface of a sheet containing at least one fibrous layer on the surface by a planar object having a plurality of openings, applying a solution of a modifier from a side of the planar object, and allowing the modifier to deposit onto a whole surface of the sheet exposed to the openings of the planar object, and a functional sheet in which sites where the modifier is deposited form projections and sites where no modifier is deposited form plains in a surface fibrous layer of the functional sheet.
