Lead frame and method for manufacturing same
 A method for manufacturing a lead frame employing a resist pattern formed on a matrix and having a cavity therein, in which an electro-deposition pattern is formed. A connecting cavity portion interconnects tip ends of inner lead cavity portions such that a connecting portion interconnects the tip ends of inner leads of the electro-deposition pattern formed in the cavity. The connecting piece is maintained while the electro-deposition pattern is separated from the matrix and the resist.
