Method of manufacturing a coil

摘要

A wind type coil has a core with a flange whose bottom surface has a recess, and an electrode is formed on the bottom surface of the flange and is extended to the recess. A wire is wound around a body of the core, and an end of the wire is welded to the electrode in the recess by thermocompression bonding or resistance welding. The wind type coil is armored by a resin armor, part of the electrode on the bottom surface of the flange being kept bare.
