Abstract:
1. A method of connecting electric wires, comprising: a step for removing coatings of a plurality of the electric wires thereby to expose conductors; a step for holding at least two places of a plurality of the electric wires; a step for twisting the conductors together in the same direction while keeping a distance between the two holding places constant, in the twisting step a force is applied to the conductors such that the conductors are compressed inward; and a step for welding the conductors together by ultrasonic welding, wherein a first electric wire from the plurality of electric wires is positioned above a second electric wire from the plurality of electric wires at one of the at least two holding places, and wherein at another of the at least two holding places the first electric wire is positioned above the second electric wire after the twisting step.
