Resin composition

A resin composition comprising the following components (A) to (D):

• (A) a first cyclic imide compound represented by:
• wherein A independently represents a tetravalent organic group having a cyclic structure, Q independently represents an alicyclic hydrocarbon group represented by:
• wherein R1, R2, R3, and R4 independently represent a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and x1 and x2 are each 0 to 4,
• wherein B independently represents any one of divalent hydrocarbon groups represented by the following formulae:
• wherein bonds that are yet unbonded to substituent groups are to be bonded to nitrogen atoms forming cyclic imide structures in the formula (1), each R1 independently represents a hydrogen atom or a linear or branched alkyl group having 1 to 20 carbon atoms, p1 and p2 are each a number of 5 or more and may be identical to or different from each other, and p3 and p4 are each a number of 0 or more and may be identical to or different from each other,
• wherein X represents a hydrogen atom or a methyl group, and
• wherein n is 1 to 200, m is 0 to 200, provided that when m is 1 or more, n:m=1:1 to 4:1, and repeating units identified by n and m may be present in any order;
• (B) a second cyclic imide compound represented by:
• wherein A independently represents a tetravalent organic group having a cyclic structure,
• wherein B independently represents any one of divalent hydrocarbon groups represented by the following formulae:
• wherein bonds that are yet unbonded to substituent groups are to be bonded to nitrogen atoms forming cyclic imide structures in the formula (3), each R1 independently represents a hydrogen atom or a linear or branched alkyl group having 1 to 20 carbon atoms, p1 and p2 are each a number of 5 or more and may be identical to or different from each other, and p3 and p4 are each a number of 0 or more and may be identical to or different from each other,
• wherein X represents a hydrogen atom or a methyl group, and
• wherein s is 0 to 200;
• (C) an epoxy compound;
• and
• (D) a curing catalyst,
• wherein the first cyclic imide compound (A) is contained in an amount of 60 to 90 parts by mass and the second cyclic imide compound (B) is contained in an amount of 10 to 40 parts by mass per 100 parts by mass of a total of the first and second cyclic imide compounds (A) and (B).
