Abstract
A connection terminal of a litz wire, a mounting method thereof, and a manufacturing method of a cooking appliance with a working coil consisting of the litz wire. The mounting method includes preparing the litz wire including plural wires, each of which includes a sheath, installing one end of the litz wire at the connection terminal, removing the sheaths from the plural wires by heating the litz wire, and deforming the connection terminal through a pinch-off process, thereby connecting front ends of the wires through the connection terminal and removing the sheaths or sheath residues between cores of the wires, and thus reducing resistance of the litz wire.
