METHOD FOR MANUFACTURING WIRE-WOUND INDUCTOR

摘要

PROBLEM TO BE SOLVED: To provide the manufacturing method of a wire-wound inductor for preventing the unfastening of insulating coating film metal wires. SOLUTION: The insulating coating film of the insulating coating film metal wire 1 is removed at a prescribed interval for exposing the surface of the metal wire. The insulating coating film metal wire 1 is densely wound, and then the insulating coating film metal wire 1 is cut for forming an air-core coil 2 having portions in each of which the surface of the metal wire is exposed at both ends. A core 5 is inserted into the air-core coil 2. Both the ends of the coil 2 into each of which the core 5 is inserted are dipped into a solder bath 35 and a solder coating film is formed on the surface of the exposed metal wire as a terminal.
