PROBLEM TO BE SOLVED: To obtain an alkoxy group-containing silane modified polyamide acid resin composition capable of providing a cured material having excellent mechanical strength and heat resistance, and a transparent polyimide-silica hybrid cured material having excellent heat resistance, mechanical strength and insulation properties and causing no warpage, nor crack. SOLUTION: This silane modified polyamic acid resin composition is characterized by comprising an alkoxy group-containing silane modified polyamide acid resin obtained by reacting a polyamic acid with an epoxy group-containing alkoxysilane partial condensate prepared by subjecting an epoxy compound containing one hydroxy group in one molecule and an alkoxysilane partial condensate to a dealcoholization reaction and a polar solvent.
