Description
本発明の枠部材付き積層シートの一実施形態を、図1Cおよび図2Bを参照して説明する。
そして、この枠部材付きインダクタ25を含む枠部材付き積層シート21では、インダクタ3が枠部材2にセットされている。そのため、たとえ、インダクタ3が小型であっても、搬送装置で搬送できる寸法を枠部材2が有すれば、枠部材3およびインダクタ2を搬送装置で確実に搬送でき、ひいては、これらを、ビア6を形成する従来の装置に搬送して、ビア6を、インダクタ3の磁性層15に確実に形成できる。また、インダクタ3が小型であれば、反りの影響を小さくできる。その結果、この枠部材付き積層シート21では、ビア6を、インダクタ3に、効率よく確実に形成できる。
以下の各変形例において、上記した一実施形態と同様の部材および工程については、同一の参照符号を付し、その詳細な説明を省略する。また、各変形例は、特記する以外、一実施形態と同様の作用効果を奏することができる。さらに、一実施形態およびその変形例を適宜組み合わせることができる。
