A cyclic olefin resin composition film having high toughness with less difference in toughness between length and width directions. The cyclic olefin resin composition film contains a cyclic olefin resin, a styrene elastomer and inorganic oxide fine particles having an average particle diameter of 40 nm or smaller, and has a linear expansion coefficient of 40 ppm/° C. to 60 ppm/° C. This film attains high toughness with less difference in toughness between length and width directions. |
