Claim 0:
1. A resin composition comprising:
(A) an epoxy resin;
(B) a cyanate resin;
(C) an aromatic amine curing agent that is liquid at 25° C.; and
(D) a phosphorus-containing compound represented by formula (1) below:, wherein, in formula (1),
m represents an integer from 1 to 10;
R1 and R2 each independently represent an alkyl group, an aryl group, or —NR4R5;
R4 and R5 each independently represent a hydrogen atom, an alkyl group, or an aryl group;
in cases where R1 and R2 are both —NR4R5, each R4 may be the same or different from one another, and R5 s may be the same or different from one another;
R3 represents a hydrocarbon group, wherein the hydrocarbon group may contain an atom selected from the group consisting of oxygen, sulfur, phosphorus, and nitrogen;
X represents an oxygen atom or a sulfur atom;
Y represents an oxygen atom, a sulfur atom, or —NR6—; and
R6 represents a hydrogen atom, an alkyl group, or an aryl group, and
wherein a blending ratio of the phosphorus-containing compound represented by formula (1) with respect to 100 parts by mass of the epoxy resin is from 20 to 100 parts by mass.
