A polymerizable resin which can form an insulating thin film excellent in heat resistance, solvent resistance, resistance to water absorption, insulation properties, lowness of permittivity, and so on. The resin is a copolymer comprising a monomer (1) represented by general formula (1) and at least one monomer selected from the group consisting of the monomers (2) to (6) represented by general formulae (2) to (6) at a weight ratio of the monomer (1) to the sum total of the monomers (2) to (6) of 5/95 to 95/5 and a number-average molecular weight of 2,000 to 1,000,000. |
