Next, in FIG. 2, a mask 2 is formed by applying a resist material to the outer surface of the coil base. Furthermore, in Figure 3, electrolysis! The fi 3 is filled with an electrolytic bath 4 and a DC voltage is applied between the coil base 1 and the electrode 5 to form an insulating ceramic 6 on the inner surface of the coil base 1 by electrodeposition. The electrodeposition method will be described in detail later. After these processing steps, as shown in FIG. 4, the coil base 1 is moved in the axial direction while rotating around its axis, and is irradiated with a high-energy laser beam 7, which reaches the insulating ceramic layer 6. The coil base layer formed of aluminum, including the mask 2, is melted and evaporated until then. Through this process, a coil 8 made of an aluminum conductor is formed on the outer layer of the insulating ceramic layer 6. After this step, as shown in FIG. 5, lead wires (preferably conductive foil) 9 are electrically connected at both ends of the coil 8 to complete the voice coil manufacturing process.
