PROBLEM TO BE SOLVED: To provide a capacitor module capable of preventing noise generated from an "electronic apparatus that may become a noise generation source" from being propagated to another electronic apparatus which is easily affected by noise, thereby preventing a malfunction from occurring in the other electronic apparatus, as a result even in the case where the "electronic apparatus that may become the noise generation source" is disposed at one side of the capacitor module and the other electronic apparatus is disposed at another side.SOLUTION: A capacitor module 1 comprises: a case 10 including a bottom face part 12 and a side face part 14 erected from the bottom face part 12; a resin 20 filling the inside of the case 10; a capacitor element 30 embedded in the resin 20; a connection electrode 60 for connecting the capacitor element 30 with an external electric circuit; and an electromagnetic wave shield member 40 which is embedded in the resin 20 while being isolated from both the capacitor element 30 and the connection electrode 60. 【課題】コンデンサモジュールの一方側に「ノイズ発生源となり得る電子機器」が配設され、他方側にノイズの影響を受けやすい他の電子機器が配設された場合であっても、当該「ノイズ発生源となり得る電子機器」から発生するノイズが当該他の電子機器に伝搬することを防ぐことが可能で、その結果、当該他の電子機器に誤動作が生じることを防ぐことが可能なコンデンサモジュールを提供する。【解決手段】底面部１２及び底面部１２から立設された側面部１４を有するケース１０と、ケース１０内に充填されている樹脂２０と、樹脂２０に埋め込まれているコンデンサ素子３０と、コンデンサ素子３０と外部の電気回路とを接続するための接続電極６０と、コンデンサ素子３０及び接続電極６０のどちらとも隔離した状態で樹脂２０に埋め込まれている電磁波シールド部材４０とを備えることを特徴とするコンデンサモジュール１。【選択図】図１
