A high-frequency induction heater based on the float zone method produces single crystal material of semi-conductor with concentric layout of high-frequency induction coils, which is characterized in: a pair of power terminals, which energize the inner heating coils with high-frequency current, being mounted in a space between the two ends of the outer heating coils; and the power terminals adhered on the inmost heating coils being spaced apart for setting conductors.
