PROBLEM TO BE SOLVED: To provide a norbornene resin molding with an antireflection film which does not peel because of tight adhesion and a method for producing the molding. SOLUTION: An antireflection film with (a) an equivalent film having an interjacent layer having 10-50 nm mechanical thickness and containing Al2O3, a 1st high refractive index layer and a 1st low refractive index layer based on SiO2 and having an overall refractive index N of 1.52-1.8 calculated from expression 1, (b) a 2nd high refractive index layer having 0.4 λ-0.6 λ optical thickness and having TiO2 as the main component and (c) a 2nd low refractive index layer having 0.2 λ-0.3 λ optical thickness and having SiO2 as the main component is formed on the surface of a norbornene resin molding having a polar group. |
