PROBLEM TO BE SOLVED: To easily install propulsion coils in side walls preventing deformation of the coils. SOLUTION: In a ground coil device for a magnetically levitated transportation system, the propulsion coils 5 to 7 and levitation coils 10 formed with cables wound around the coils are installed in the side walls 2 of a track 1 so that these coils may be opposite each other, then superconducting coils 4 mounted on the magnetically levitated vehicle 3 and the propulsion coils 5 to 7 are arranged oppositely with the levitation coils 10 placed therebetween. The coil device includes spools 8 of resin and fixing means 11, wherein the spools are provided with installing portions to be fixed to the side walls 2, and are wound by the propulsion coils 5 to 7 around the spools, and fixing means fix the propulsion coils 5 to 7 and the levitating coils 10 to the side walls 2 through the installing portions of the spools 8 so that the propulsion coils 5 to 7 may be pressed by the levitating coils 10.
