A method for manufacturing a power distribution member includes preparing a solid wire with a circular cross-sectional shape, pressing to a portion of the solid wire in a pressing direction orthogonal to the solid wire to cause plastic deformation, thereby forming a pair of small curvature surfaces on an outer circumference of the solid wire on both sides in the pressing direction, the small curvature surfaces having a smaller curvature than an outer circumferential surface of the solid wire before the pressing and facing the pressing direction, preparing a terminal metal piece including a pair of facing walls facing each other and a coupling wall coupling between ends of the pair of facing walls, inserting the solid wire after the pressing between the pair of facing walls of the terminal metal piece in such a manner that one of the pair of small curvature surfaces faces one of the pair of facing walls and the other of the pair of small curvature surfaces faces the other of the pair of facing walls, and, after the inserting, crimping the pair of facing walls onto the solid wire.
