1. A method for manufacturing a power distribution component for use in a predetermined position of an electric device, the method including the steps of: processing a round metallic wire formed of a cross section circular solid wire for use as a conductor of the power distribution component, wherein:
a correction step of linearly correcting a coiled material of the round metallic wire;
a cross-section non-circular portion forming step of forming a cross-section non-circular portion having a non-circular cross-sectional shape in a diameter direction in at least one position of the round metallic wire linearly corrected by the correction step; and
a bending step of holding the cross-section non-circular portion in a wire holding portion of a bending machine and performing bending in a predetermined three-dimensional shape, and the method further comprising the step of:
integrally attaching a resin member on an outer periphery of the cross-section non-circular portion of the processed product of the round metallic wire,
wherein in the cross-section non-circular portion forming step, the cross-section non-circular portion is processed in a shape including a flat surface which comes into surface contact with an abutting surface of the wire holding portion of the bending machine.
