Claim:
1. A manufacturing method of an electronic component including a substrate and an element electrode provided on the substrate, the element electrode including functional electrode portions and pad portions connected to the functional electrode portions, the method comprising: forming a plurality of the element electrodes and feed lines on a mother substrate for forming the substrate such that each of the pad portions of the plurality of element electrodes and the corresponding one of the feed lines are not electrically connected to one another, each of the pad portions of the plurality of element electrodes and a portion of the corresponding one of the feed lines face each other with a gap therebetween when viewed in a plan view such that each of the portions of the feed lines surrounds a respective one of the pad portions, and a top surface of the feed lines is disposed lower than a top surface of the pad portions when viewed in a cross sectional view; performing electrolytic plating while supplying power to the feed lines, to form a plating film that electrically connects the feed lines and the pad portions; and singulating the mother substrate to obtain the electronic component.
