Abstract:
[Problem] To provide a functional sheet that allows for easy erasure and correction of ink applied to a surface thereof while impeding erasure after a certain amount of time, and to provide a production method therefor. [Solution] The invention provides a sheet member whereby permeation of a liquid may be controlled, having a sheet surface layer 3 positioned on a base material surface layer. The sheet surface layer 3 is provided with a flow path 3h whereby permeation of a liquid, inward from the surface 3s of the sheet surface layer 3, may be controlled. Since the sheet surface layer 3 is provided with the flow path 3h whereby permeation of a liquid may be controlled, the erasing time for liquid applied on the sheet surface can be controlled.
