    • PURPOSE: An aromatic polyimide-based resin has improved chemical resistance by introducing an allyl group or a vinyl group into a polyimide basic frame structure, maintains excellent thermal resistance, and improves the thermal shrinkage or expansion ratio. CONSTITUTION: An aromatic polyimide-based resin is represented by chemical formula 1. A manufacturing method of the aromatic polyimide-based resin comprises a step of manufacturing an allyl group or a vinyl group side chain-containing polyamic acid resin represented by chemical formula 2 by polycondensating an allyl group or a vinyl group-containing diamine compound represented by chemical formula 3 or the mixture of the diamine compound and a diamine monomer represented by chemical formula 4 with an acid dianhydride; and a step of manufacturing the aromatic polyimide-based resin crosslinked and imidized by the aryl group or vinyl group side chain by heating and curing the polyamic acid resin.
