PROBLEM TO BE SOLVED: To provide a manufacturing method capable of manufacturing a cylindrical, columnar and tabular resin dielectric which is reduced in cost and is excellent in dielectric characteristic, using a resin material mixing a dielectric ceramic powder with a fluorine resin powder of PTFE resin and the like. SOLUTION: The manufacturing method of the resin system dielectric comprises a mixing step for mixing at least the fluorine resin powder and the dielectric ceramic powder into a mixture; and a molding step for molding the mixture into a cylindrical, columnar and tabular compact by means of a ram extrusion molding method. The fluorine resin powder is at least a powder selected from the PTFE resin and the denatured PTFE resin. The dielectric ceramic powder is mixed at the mixing step with a ratio of 5 to 50 vol% in a total of mixture. The obtained resin dielectric is not smaller than 3 in specific permittivity and not larger than 0.01 in dielectric tangent under a frequency of 1 GHz or less and a temperature of 25°C.
