Claim:
1. A resin composition containing a polyimide-based resin and a methylol-based compound, wherein the polyimide-based resin has an acid dianhydride residue and a diamine residue; the diamine residue is at least a residue of a polysiloxane-based diamine represented by general formula (1) and a residue of an aromatic diamine having an hydroxyl group, wherein n is a natural number, and an average value thereof calculated from an average molecular weight of the polysiloxane-based diamine is in a range of 5 to 30, R 1 and R 2 may be individually the same or different and indicate an alkylene group or a phenylene group having a carbon number that is 1 to 30, R 3 to R 6 may be individually the same or different and indicate an alkyl group, a phenyl group or a phenoxy group having a carbon number that is 1 to 30; and the resin composition has a glass transition temperature after curing that is less than or equal to 40° C.
