Abstract
【解決手段】封止樹脂134は、電子部品17,18が収容された貫通部141を充填するように配置されている。封止樹脂134は、電子部品17,18の背面17A,18Aを露出している。封止樹脂134は、電子部品17,18の側面を覆っている。これにより、封止樹脂134は、電子部品17,18の側面部を封止している。封止樹脂134の上面134Aは、平坦な面とされている。封止樹脂134の上面134Aは、電子部品17,18の背面17A,18A及び絶縁部材133の上面133Aと略面一になるように構成されている。封止樹脂134の厚さは、絶縁層41の上面41Aに配置された部分の電子部品17,18の厚さ及び絶縁部材133の厚さと略等しい。
