Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an adsorptive film having an adsorption power as well as transparency.SOLUTION: An adsorptive film includes, on a surface of a flexible film 10 with porosity of 0-50%, a plurality of concavities 20 each having an opening with an average diameter of 0.05-10 μm. A proportion of an area of the openings is 30-80% with regard to a total area of a region having the concavities 20 on the surface of the flexible film 10.
