Abstract:
A lead frame has a concavity formed on the upper-surface side of a metal plate and columnar portions  3  defined by the concavity. A horizontally deepest portion regarding a side face shape of the concavity is positioned lower than the vertical center position of the concavity. Thereby, overhangs projecting from the top faces of the columnar portions rarely cause shape defects or burr defects and thus the lead frame has an enhanced capability, by the columnar portions, of preventing a sealing resin from coming off without sacrificing the freedom of wiring design.

Claim (Index 6):
The method for manufacturing a lead frame according to  claim 4 ,\n wherein, in the step of forming the resist mask, the resist mask covering the plating layer on the front-surface side of the copper plate is formed such that the copper plate is left uncovered for 5 to 30 \u03bcm around an edge of the plating layer on a top face of each of the columnar portions.
