ABSTRACT:
The claimed invention provides an ultrasonic welding method, whereupon joint portions in which a copper foil portion and a twisted-wire electric cable are placed one upon the other in each groove of a resin casing, the grooves having a through-hole portion. In the through-hole portion, the copper foil portion and the twisted-wire electric cable are placed one upon the other. Welding is performed in a state in which the piled-up portion is sandwiched between a welding tip formed at an end of a welding head and an anvil. Thus, the joint portion between the copper foil portion and the twisted-wire electric cable invade and are invaded by a portion of the resin casing softened by welding heat. The joint portion is fastened not only by welding, but also by the solidified resin.
