イル。 The lower leads, which are made by bending a thin flat plate of the required width into a U-shape and are arranged in multiple rows at the required pitch, are placed symmetrically opposite each other at the required intervals. The vertical sides of the square annular cores are inserted into each other, and thin flat plates of the required width are arranged in multiple rows at the required slope so that the cores are sandwiched vertically and continuous coils are formed from side to side for each lower lead. Then, one upper lead with an integrated electrode plate on the front end and the other upper lead with an integrated electrode plate on the rear end are welded and connected to the respective lower leads, and the rear end of one upper lead is connected to the other upper lead. A normal mode chain yoke coil formed by molding a normal mode winding connected to the front end of a lead, and encapsulating the coil having the winding in a resin layer.
