Claim Text:
1. A reactor comprising: a central core member made of a magnetic material, extending in an axial direction; a plurality of coils arranged around the central core member; and a core member serving as a path for magnetic flux that is generated when electric power is supplied to the coils, wherein the coils are constituted by respectively winding band-like conductor members to be layered with an insulating member interposed between windings of the conductor members such that a width direction of the conductor members is matched with said axial direction of the central core, and the core member is formed of a wire made of a magnetic material and is arranged outside the coils such that the coils are enclosed in a space formed by inner surface of the core member and the outer surface of the central core member and the wire of the core member is wound into a shape of a ball of string or yarn while surrounding the coils, wherein the wire of the core member is arranged such that a lengthwise direction of the wire is substantially matched with a direction of the magnetic flux generated when AC power is supplied to the coils, and each of said band-like conductor members has a width in the axial direction of the central core which is substantially the same as a dimension between the opposite ends of inside of the core member along the axial direction of the central core.
