A covered electric wire is placed on a conductor drawn out onto a terminal retaining portion protruding from an end portion of a connector housing. A a core wire of the covered electric wire is conductively contacted with the conductor and welding ribs on both sides of a cover closing the terminal retaining portion are welded to the terminal retaining portion by oscillating ultrasonic waves while pressing the covered electric wire against the conductor by means of this cover. On an outer periphery of the cover there is formed a reinforcing rib covering the length between the welding ribs on both sides thereof.
