The resin composition of the present invention is a resin composition containing: a bismaleimide compound (A) containing a constituent unit represented by the following formula (1) and maleimide groups at both ends of the molecular chain; a compound (B) containing one or more carboxy groups; and a photo initiator (C).
In the formula (1), R1 represents a linear or branched alkylene group having 1 to 16 carbon atoms, or a linear or branched alkenylene group having 2 to 16 carbon atoms. R2 represents a linear or branched alkylene group having 1 to 16 carbon atoms, or a linear or branched alkenylene group having 2 to 16 carbon atoms. Each R3 independently represents a hydrogen atom, a linear or branched alkyl group having 1 to 16 carbon atoms, or a linear or branched alkenyl group having 2 to 16 carbon atoms. Each n independently represents an integer of 1 to 10.
