Abstract: A cyclic olefin resin film which has heat resistance and improved brittleness. A heat-resistant transparent film which has an internal haze value of 1.0% or less and contains a cyclic olefin resin having a refractive index of n1 and a glass transition temperature (Tg) of 170° C. or more and a styrene elastomer that has a refractive index of n2 so that Δn=|n2−n1| is 0.012 or less. The heat-resistant transparent film may contain two or more kinds of styrene elastomers, and the cyclic olefin resin may be a copolymer of norbornene and ethylene.
