PURPOSE: An apparatus for a plastic-deformation of a lead frame is provided to improve the deforming work of the lead frame and to increase the productivity of articles by preventing the spring back when the plastic-deformation of the lead frame is carried out. CONSTITUTION: A lead frame deforming apparatus has a press member(50) which presses the lead frame by a punch to deform the lead frame in a desired shape. The lead frame is rested on a support member(60) having a die plate(64). Both ends of the die plate(64) of the support member(60) are rounded and the surface of the die plate(64) are surface-treated to a predetermined shape. A concave recess(61) is formed on the surface of a female deforming section(62) of the support member(60) so a down-set work of the lead frame is effectively carried out.
