Abstract
A cyclic olefin-based copolymer resin composition includes a cyclic olefin-based copolymer (M); and a maleimide compound (L), in which the cyclic olefin-based copolymer (M) includes a cyclic olefin-based copolymer (m) including a repeating unit represented by a specific general formula, the maleimide compound (L) has a solubility parameter (SP value) obtained by Fedors method of 19 J1/2/cm3/2 or more and 26 J1/2/cm3/2 or less and includes a maleimide compound (l), which is a bismaleimide compound having at least two maleimide groups in a molecule, and when a total of the cyclic olefin-based copolymer (M) and the maleimide compound (L) is 100 parts by mass, a content of the maleimide compound (L) is 1 part by mass or more and 50 parts by mass or less.
