Abstract
A lead frame includes a dam bar and leads connected by the dam bar. Each lead includes an inner lead, which is located at one side of the dam bar, and an outer lead, which is located at the other side of the dam bar and formed integrally with the inner lead. Each inner lead includes a basal portion located at a side closer to the dam bar, a distal portion located at the opposite side of the basal portion, and an intermediate portion connecting the distal and basal portions and having a width that differs from the distal portion. A plating layer covers an upper surface and a side surface of the distal portion and at least part of a side surface of the intermediate portion. Side surfaces of the basal portion and the dam bar are entirely located outside the plating layer.
