In the figure, the same reference numerals as in Figures 1 and 2 indicate the same or equivalent parts, and (3) indicates two pieces of iron core (1) that are melted and fixed by locally heating the end face of the core (1) in the stacking direction. The conductor (3a) is formed, and the core end face (IC)
is further melted and fixed by local heating in a direction perpendicular to the conductor (6a), and the ends of the conductor (3a) are short-circuited to form an annular shaded coil. In addition, the core end face (
1C) The local heating process can be performed by, for example, laser processing or TIG arc welding.
