Abstract
The purpose of the present invention is to control the lamination thickness of the laminated core of an axial gap rotating electric machine. The axial gap rotating electric machine is provided with: a stator comprising a plurality of core members arranged circularly about the rotational axis center, said core members each comprising a columnar-laminated core having a flux surface in a rotation axis direction, a coil disposed on the outer perimeter of the core in the radial direction, and a substantially cylindrical bobbin disposed between the core and the coil; and at least one rotor facing the flux surface with a predetermined gap interposed therebetween in the rotation axis direction. The bobbin has an inner cylinder facing the outer perimeter of the core in the radial direction, and at least part of the inner diameter of the inner cylinder becomes gradually smaller along the rotation axis direction and makes contact with the outer perimeter surface of the laminated core in the radial direction.
