PURPOSE:To protect outer leads from external force, and to prevent the bending of the outer leads by obliquely cutting a frame section positioned at a section where the outer less mutually penetrate so that the noses of the outer leads are not projected. CONSTITUTION:Frame 1 sections corresponding to sections where outer leads 5 for lead frames in adjacent units mutually penetrate are cut in the directions oblique to the longitudinal directions of the frame 1 sections. Consequently, frames 11 for protection protecting the leads 5 from external force are formed outside the leads 5. Accordingly, the leads 5 are protected from external force, and the bending of the leads 5 is prevented. |
