A motor comprising a stator having a plurality of magnetic poles disposed in a circumferential direction along an outer periphery thereof, a rotor disposed rotatably around the outer periphery of the stator, and a magnet disposed in a circumferential direction along an inner periphery of the rotor. The stator is formed by laminating sheet-like plates. A plurality of the sheet-like plates including an outermost layer of this laminated body comprises a flat portion substantially perpendicular to the magnet, and an extended portion bent to a direction substantially parallel to the magnet. A part of the sheet-like plate having the extended portion disposed to the outermost side is formed into a thickness smaller than thicknesses of the other parts.

Motor and electronic device comprising the same

The motor of the invention is an outer rotor type motor, and a rotor includes a cylindrical rotor frame that is opened at one end thereof in an axial direction, and a hollow cylindrical magnet attached to an inner periphery of the rotor frame. The magnet has a joining portion joined to an inside cylindrical portion of the rotor frame, and a protruding portion that further protrudes in the axial direction from one end, the outer diameter of the protruding portion is larger than the inner diameter of the rotor frame, and the joining portion is directly brought into close contact with a portion ranging from the one end to at least a portion of the inside cylindrical portion.
