Claim 0:
1. An electrical cable manufacturing method comprising:
setting an interval between a first facing surface and a second facing surface in a first direction to a first distance, in a joining device including the first facing surface and the second facing surface facing each other in the first direction, and a pressing member and a vibrating member facing each other in a second direction orthogonal to the first direction;
placing a plurality of core wires between the first facing surface and the second facing surface having the interval set at the first distance; and
joining the core wires by using the vibrating member to apply ultrasonic vibration to the core wires while sandwiching the core wires between the pressing member and the vibrating member, wherein
the core wires include core wires having outer diameters having mutually different values, and
the first distance is larger than a maximum value between values of outer diameters of the core wires and smaller than a sum of the maximum value and a minimum value between the values of the outer diameters of the core wires.
