PROBLEM TO BE SOLVED: To provide a soldering method by which conductors can be connected favorably to electrodes in a state where the surfaces of the electrodes are not eroded. SOLUTION: A coil is equipped with a winding 2 composed of a conductor and an insulating film coating the conductor and electrodes 5. On the surfaces of the electrodes 5, plated surface films composed of plated nickel films having thicknesses of >=0.5μm are formed. The conductors are connected to the electrodes 5 by soldering by adjusting the soldering temperature and dipping time so that the plated nickel films may not be eroded and the insulating films may be melted, and then, the constituent metals of the conductors and electrodes may form an alloy with the component of the solder. |
