The purpose of the present invention is to efficiently cope with the plate thickness deviation of a laminated iron core in an axial air gap type electric motor. An axial air gap type electric motor comprises: a stator formed by arranging stator cores (6) around a rotating shaft (4) in a ring shape, said stator cores (6) each including a laminated iron core (8) that is a prismatic body formed by laminating metal plate-like members in a radial direction of the rotating shaft, a tubular bobbin (7) that has an inner diameter into which the laminated iron core is inserted, and a coil (9) that is wound on the extension of the outer diameter of the laminated iron core; and at least one rotor (3) plane-facing the rotating shaft direction end section of the stator with a predetermined air gap interposed therebetween. The laminated iron core includes: a portion (core member (10b)) formed by continuously laminating the metal plate-like members, the widths of which increase in a rotational direction of the rotating shaft from the rotating shaft center toward a radial direction; and a portion (core member (10a)) formed by continuously laminating the metal plate-like members, the widths of which are substantially equal. |
