In order to produce a ground coil for a magnetically levitated railway, coils each composed of a conductor coiled in a plurality of turns are arranged in a metal mold, and a synthetic resin forming reactive liquid is injected and cured in the metal mold by reaction injection molding. Furthermore, a plurality of base coils are produced each composed of a coil conductor coiled in a plurality of turns in a desired shape, laid in two tiers and connected in series so as to form unit coils. Two unit coils are connected so that the winding directions of them are opposite to each other and guidance terminals are formed, thereby forming a pair of levitation and guidance coils. Two pairs of levitation and guidance coils are arranged on a single plane in a metal mold so that the positional relationship among the coils is constant, and a synthetic resin forming reactive liquid is injected and integrally cured by reaction injection molding.
