Abstract

【課題】 未硬化の封止用樹脂がスルーホール電極の開口内に流れ込むのを防止して、信頼性の高い電子部品を提供すること。 【解決手段】 スルーホール電極付き電子部品100は、上面に電極パターン2が形成され、下面に電極端子3が設けられた回路基板1と、回路基板1の上面から下面まで貫通し、電極パターン2と電極端子3とを導通させるスルーホール電極4と、スルーホール電極4の上面側の開口部の周囲に設けられるレジスト層11と、少なくともスルーホール電極4およびレジスト層11の上面を覆って設けられるドライフィルム12と、回路基板1の上面を封止する封止用樹脂20とを有する。 【選択図】 図2
PROBLEM TO BE SOLVED: To prevent non-hardened sealing resin from flowing into the opening of a through hole electrode, and to provide a highly reliable electronic component. SOLUTION: The electronic component with a through hole electrode 100 is provided with a circuit board 1 where an electrode pattern 2 is formed on an upper face and an electrode terminal 3 is installed on a lower face, a through hole electrode 4 which penetrates from the upper face and the lower face of the circuit board 1 and conducts the electrode pattern 2 and the electrode terminal 3, a resist layer 11 arranged at a periphery of the opening part on an upper face-side of the through hole electrode 4, a dry film 12 disposed by covering the upper faces of the through hole electrode 4 and the resist layer 11, and sealing resin 20 sealing the upper face of the circuit board 1.
