PURPOSE:To use a bonding wire having high current conductivity and high reliability for a pad wherein a large current flows by using bonding wires having different current conductivities properly for each pad. CONSTITUTION:Among pads 11, a relatively large current flows in a pad 11a and a relatively small current flows in a pad 11b. Among lead parts 31, a lead part 31a is connected to the pad 11a and a lead part 31b is connected to the pad 11b. A bonding wire 20a which connects the pad 11a and an inner lead 312a of the lead part 31a consists of copper having high current conductivity to withstand a relatively large current. A bonding wire 20b which connects the pad 11b and an inner lead 312b of the lead part 31b consists conventionally of gold. |
