An armature core includes a core portion formed of a lamination of plural noncrystalline metallic foil bands and resin for bond-fixing the non-crystalline metallic foil bands, wherein the armature core is provided with at least two cut surfaces with respect to the lamination layers. Amorphous metal is used as the iron base of the non-crystalline metallic foil bands. The cut surfaces are perpendicular to the lamination-layers of the non-crystalline foil bands. For the amorphous core, a resin mold is formed. The contact portions between winding wires and amorphous are provided with edge roundness. Further, an axial gap motor using cut cores of amorphous lamination as stator cores is provided. Still further, the stator includes: a plurality of stator cores in a bar shape, the stator cores being disposed along circumferential direction, wherein the axial line of the rotor shaft is the central axis of the circumferential direction, and wherein an axial direction of the stator cores is along the axial line direction AX of the rotor shaft; a stator core holding member in a disc form, the stator having a plurality of holes or recessions that are substantially in the same shape as a cross-sectional shape of the stator cores and are arranged along the circumferential direction, wherein the axial line of the rotor shaft is the central axis of the circumferential direction; and coils wound around the stator cores, and wherein the stator cores are inserted in the holes or recessions of the stator core holding member and held by fixing in vicinities of respective central portions thereof, the central portions being with respect to the axial direction thereof.
