Provided is a resin composition having good solubility in a low boiling point solvent such as methyl ethyl ketone and good storage stability. The content of the (A) polymaleimide compound in 100 parts by mass of the resin mixture containing the (A) polymaleimide compound and the (B) benzoxazine compound represented by the formula (1) is 30 to 95 parts by mass. , A resin composition produced by a melt-mixing step of melt-mixing the resin mixture. [Chemical 1] (In the above formula (1), n 1 is an integer of 0 or more and 10 or less, and X 1 is an alkylene group having 1 or more and 10 or less carbon atoms independently, a group represented by the following formula (2), and the formula "-". A group represented by "SO 2- ", a group represented by "-CO-", an oxygen atom or a single bond, R 1 is an independently hydrocarbon group having 1 or more carbon atoms and 6 or less carbon atoms, and a is Each is an integer of 0 or more and 4 or less independently, and b is an integer of 0 or more and 3 or less independently.) [Chemical 2] (In the above formula (2), Y is a hydrocarbon group having an aromatic ring and having 6 to 30 carbon atoms, and n 2 is an integer of 1 to 3). |
