PROBLEM TO BE SOLVED: To provide a flexible high-performance organic field-effect transistor manufacturable inexpensively through a simple process by combining a specific plastic substrate with a specific resin insulation layer. SOLUTION: The organic field-effect transistor includes, on an insulating support substrate 1, the insulation layer 3, a gate electrode 2 and an organic semiconductor layer 4 isolated from each other by the insulation layer 3, and a source electrode 5 and a drain electrode 6 formed to contact the semiconductor layer 4. The insulating support substrate 1 is formed of polyethylene terephthalate. The insulation layer 3 is formed of one or more kinds selected among polystyrene, polyvinyl phenol, polycarbonate, polyester, polyvinyl acetate, polyurethane, polysulfone, methacrylic resin, epoxy resin, hydrocarbon resin having a cyano group, and phenol resin.
