PROBLEM TO BE SOLVED: To provide a flat type coreless motor by which output characteristics are improved to much extent with simple configuration, without increasing a rating of the motor. SOLUTION: The flat type coreless motor includes a planar type armature and a magnet. In the armature, a plurality of single coils, each of which is wound in a round shape or a polygon shape, are arranged annularly around a rotating shaft on a plane which is vertical in a rotating shaft direction, and are molded with resin. The magnet is arranged annularly, in the rotating shaft direction at least at one face side of planes of the armature and arranged oppositely to one face through an air gap. Either of the armature or the magnet is rotatably borne by a bearing to the other, wherein a magnetic powder is mixed in the resin, and when the armature is molded with the resin, it is molded in such a state where a magnetic field is applied to the resin, by which the magnetic powder is magnetized and arranged in a fixed direction causing the armature itself to generate magnetic operation.
