Abstract

This resin composition is characterized by comprising (a) 100 parts by mass of a polyimide precursor containing a structural unit represent by general formula (1) (wherein, R1 and R2 are each independently selected from a hydrogen atom, monovalent aliphatic hydrocarbons having 1-20 carbon atoms, and aromatic groups, and X1 is a tetravalent organic group having 4-32 carbon atoms), (b) 0.001-5 parts by mass of a silicone-based surfactant, and (c) an organic solvent.
