SOLID ELECTROLYTIC CAPACITOR, AND MANUFACTURING METHOD THEREOF

PROBLEM TO BE SOLVED: To simplify a step of insulating a capacitor element and a terminal board with a sealing resin and to improve an insulation performance and airtightness.SOLUTION: In a capacitor element 10, a cathode part and an anode part disposed around the cathode part are provided on at least one surface of an anode body 11 made from a valve action metal. In the cathode part, a dielectric oxide coating layer, a solid electrolyte layer and a cathode leading-out part 14 are sequentially formed, and in the anode part, an anode leading-out part 13 is formed. In a terminal board 20, an anode electrode part 22 and a cathode electrode part 21 are formed while being electrically insulated with an insulative resin 23. A surface of the cathode electrode part 21 is covered with a sealing resin 30. In a state where the cathode leading-out part 14 and the cathode electrode part 21 are made opposite and the anode leading-out part 13 and the anode electrode part 22 are made opposite, the capacitor element 10 and the terminal board 20 are overlapped. The cathode leading-out part 14 penetrates the sealing resin 30 and is electrically connected to the cathode electrode part 21. 【課題】封止樹脂によるコンデンサ素子と端子板との絶縁工程を簡便にする。絶縁性能および気密性の向上を可能とする。【解決手段】コンデンサ素子１０に、弁作用金属からなる陽極体１１の少なくとも片面に、陰極部とその周囲に配置された陽極部を設ける。陰極部には、誘電体酸化皮膜層、固体電解質層、陰極引出部１４を順次形成すると共に、前記陽極部に陽極引出部１３を形成する。端子板２０に、陽極電極部２２および陰極電極部２１を絶縁性樹脂２３により電気的に絶縁された状態で形成する。陰極電極部２１の表面を封止樹脂３０によって被覆する。陰極引出部１４と陰極電極部２１、陽極引出部１３と陽極電極部２２が対向した状態でコンデンサ素子１０と端子板２０を重ね合わせる。陰極引出部１４が封止樹脂３０を貫通して陰極電極部２１に電気的に接続されている。【選択図】図１
