PURPOSE:To facilitate the inspection of the displacement of a mount by forming a projection toward a lead at the end around a base for mounting a semiconductor element. CONSTITUTION:Projections 6 toward at least one or more leads are formed on the periphery of a base 2 for placing a semiconductor element 1 of a lead frame. In this manner, pin number can be readily identified, and when the length of the projec- tion is suitably selected, the displacement of the mount can be detected with the length as a reference, thereby improving the efficiency in the assembling work of the semiconductor device. |
