The cyclic olefin copolymer composition of the present invention includes a cyclic olefin copolymer (m) including a specific amount of a specific repeating unit and a cyclic olefin copolymer (n) different from the cyclic olefin copolymer (m). The cyclic olefin copolymer (n) includes at least one type selected from a copolymer (n1) of ethylene or α-olefin and cyclic olefin (where the copolymer (n1) does not include a repeating unit derived from specific cyclic non-conjugated dienes) and a cyclic olefin ring-opening polymer (n2), and when a total amount of the cyclic olefin copolymer (m) and the cyclic olefin copolymer (n) is 100% by mass, a content of the cyclic olefin copolymer (m) is 5% by mass or more to 95% by mass or less, and a content of the cyclic olefin copolymer (n) is 5% by mass or more to 95% by mass or less.
