Welded article and method for manufacturing welded article

A method for manufacturing a welded article, comprising the steps of:

• providing a first welding target member including an elongated projection portion having short sides and long sides that are longer than the short sides;
• providing a second welding target member to be bonded to the first welding target member by welding;
• and
• bringing the projection portion into contact with the second welding target member and bonding the first and second welding target members by resistance welding,
• wherein the projection portion has a plurality of subdivided projection portions separated by subdividing grooves formed into the projection portion at different positions along the long sides of the projection portion, in order to improve the uniformity of current values in the direction of the long sides of welding currents flowing through the subdivided projection portions;
• the subdivided projection portions are in parallel, the subdividing grooves extend into a part located adjacent to the projection portion where the part located adjacent to the projection portion does not contribute to welding, and the part located adjacent to the projection portion is a part extended in parallel from the projection portion to the bottom of the subdividing grooves,
• wherein the first welding target member includes two end portions in the direction of the long sides.
