第2リード3は、後述の導通部材61が接合される部材である。第2リード3は、導電性材料である第1金属よりなる。本実施形態における第1金属としては、たとえばCuが挙げられるが、これに限定されず、Ni(ニッケル)、または、CuやNiの合金、42アロイなどであってもよい。第2リード3は、平面視矩形状のCuなどの薄肉金属板から、打ち抜き加工、切り取り加工、曲げ加工などにより適切な形に形成される。図1~図4、および図6に示すように、本実施形態の第2リード3は、第2パッド部31および端子部32を有する。
第2リード4は、後述の導通部材62が接合される部材である。第2リード4は、導電性材料である第1金属よりなる。本実施形態における第1金属としては、たとえばCuが挙げられるが、これに限定されず、Ni(ニッケル)、または、CuやNiの合金、42アロイなどであってもよい。第2リード4は、平面視矩形状のCuなどの薄肉金属板から、打ち抜き加工、切り取り加工、曲げ加工などにより適切な形に形成される。図1~図3、図5および図11に示すように、本実施形態の第2リード4は、第2パッド部41および端子部42を有する。
導通部材61は、半導体素子1のゲート電極111と第2リード3とを導通させるためのものである。導通部材61の具体的構成は何ら限定されず、たとえば金属からなるワイヤやリボンが挙げられる。導通部材61を構成する金属としては、たとえばAu、Al等の金属やこれらの合金が挙げられる。Al合金としては、たとえばAlにFe、Si、Niのいずれかが添加されたAl合金が挙げられる。本実施形態においては、導通部材61は、Auからなるワイヤである。
