Abstract
A lead frame includes a die pad, a suspension lead and a plurality of leads. The group of leads include at least three kinds of leads, including first, second and third leads. While the first lead and the third lead are connected to each other upon production of the lead frame, a connecting portion therebetween has a smaller thickness than that of the frame body so that the first lead and the third lead can be separated from each other in a subsequent step.
