A winding apparatus includes a nozzle for feeding a wire to a first end side of a magnetic pole in a winding position, a first latch pawl capable of latching the wire fed from the nozzle, a first latch pawl moving mechanism that moves the first latch pawl from the first end side to a second end side of the multi-pole armature, and a nozzle moving mechanism that moves the nozzle in both the radial direction and the circumferential direction of the multi-pole armature. A width of the first latch pawl in the circumferential direction of the multi-pole armature is set at a width enabling insertion of the wire wound around and bent back by the first latch pawl into slots formed on both sides of one or more of the magnetic poles in the winding position.

A method for manufacturing an electronic component for avoiding electromagnetic interference includes: (a) placing a T-shaped core and an air-core coil in a metal mold; (b) injecting a mixture of a composite magnetic material and a resin into the metal mold so that the T-shaped core and the air-core coil are embedded by the mixture; (c) heating the mixture at a first temperature; (d) adjusting an outer shape while removing excessive mixture; and (e) hardening the mixture. The method may further include a process of polishing an outside of the hardened mixture. The method may further include a process of applying a pressure of 0.1 to 20.0 kg/cm.sup.2 to the mixture for adjusting an outer shape of the mixture by a movable punch of a press machine before the hardening process.
