Abstract
In a protective film affixed to a microscopic roughness structure having a microscopically rough structure on the surface, water contact angle of the surface of the microscopic roughness structure is 40° or less, compressive stress obtainable when the adhesive layer of the protective film is compressed to a compression ratio of 20% is 0.6 MPa to 3.0 MPa; in the infrared absorption spectrum of the surface on the microscopically rough structure side of the microscopic roughness structure, ratio (A1/A2) of peak area A1 having absorption maximum of 3700 cmto 3100 cm, and peak area A2 having absorption maximum of 1730±10 cm, is 0.1 to 0.8; in the surface of adhesive layer of the protective film, ratio (B1/B2) of peak area B1 having absorption maximum of 3700 cmto 3100 cm, and peak area B2 having absorption maximum of 1730±10 cm, is 0.6 to 1.3.
