The invention provides a transparent conductive substrate using allyl ester heat-curable resin, comprising a compound having a group represented by formula (2) as terminus and a group represented by formula (3) as repeating unit, (In the formulae, R<3>A<2 >and A<3> have the same meanings as defined in the Description). The transparent conductive substrate is useful as a plastic substrate for display device, characterized by excellent heat resistance and chemical resistance, a low average linear expansion coefficient and high transparency, where warpage, deformation, crack of wiring are hard to occur in a process of thin film device formation.
