A manufacturing method for manufacturing a welded article by bonding a first welding target member including an elongated projection portion on a welding target portion having short sides and long sides that are longer than the short sides and a second welding target member by resistance welding, in which the projection portion of the first welding target member is subdivided by forming subdividing grooves extending in the direction of the short sides in the projection portion to reduce the influence of skin effect on the welding current flowing through the subdivided projection portions and improve the uniformity of the current values in the direction of the long sides.
