摘要： [Object] To provide a transparent film for a face protection shield in which transparency is enhanced and visibility from a non-wearer is also enhanced.
[Solution] A transparent film for a face protection shield including: a transparent base material having flexibility; and a transparent resin layer configured to be laminated on at least one of surfaces of the transparent base material, the transparent resin layer having on a surface a plurality of structural bodies including concavities or convexities provided at a pitch of less than or equal to a visible light wavelength. A refractive index of the transparent base material is different from a refractive index of the transparent resin layer, and an interface between the transparent base material and the transparent resin layer has a concave-convex shape.
