PURPOSE:To prevent the separation of wire bonding parts, by forming buffer parts whose strength is partially weak in inner leads. CONSTITUTION:The wire bonding parts 12 are formed at the tips of the inner leads 2 of two leads 1 on both sides. Protruded parts 3 which are hooked to a resin are provided on the 3 inner leads 2. The thin buffer parts 13 whose strength is the weakest are provided on the inner leads 2 of the 2 leads for wire bonding. When an external force is applied to the lead 1, the lead is not pulled out since the hooking part of each inner lead 2 is hooked to the resin. Since the strength of the buffer parts 13 for the inner leads 2 is weak, they are extended and deformed by the external force and absorb the external force. |
