ELECTROLYTIC CAPACITOR AND METHOD FOR MANUFACTURING THE SAME

To improve reliability of an electrolytic capacitor.SOLUTION: An electrolytic capacitor includes a capacitor element 10 having an anode part and a cathode part, an anode terminal 13 electrically connected to the anode part, a cathode terminal 14 electrically connected to the cathode part, and an exterior body 11 covering the capacitor element in a state in which a part of the anode terminal 13 and a part of the cathode terminal 14 are exposed. The capacitor element 10 has a first main surface S1, a second main surface S2 sharing one side of the first main surface, and a third main surface that shares the one side of the first main surface and is positioned on a side opposite to the second main surface. The cathode terminal 14 has a loading part 14a which is mounted with the capacitor element and is opposite to the first main surface S1, and a side wall part 14c which is bent from the loading part 14a, and extends in a direction crossing the first main surface S1. The exterior body 11 has a resin injection mark, and the resin injection mark is positioned at a position opposite to the side wall part 14c.SELECTED DRAWING: Figure 1 【課題】電解コンデンサの信頼性を向上させる。【解決手段】電解コンデンサは、陽極部および陰極部を備えるコンデンサ素子１０と、陽極部と電気的に接続する陽極端子１３と、陰極部と電気的に接続する陰極端子１４と、陽極端子１３の一部、および、陰極端子１４の一部を露出させた状態で、コンデンサ素子を覆う外装体１１と、を備える。コンデンサ素子１０は、第１主面Ｓ１と、第１主面と一辺を共有する第２主面Ｓ２と、第１主面と一辺を共有し、且つ第２主面と反対側に位置する第３主面と、を有する。陰極端子１４は、コンデンサ素子が搭載される、第１主面Ｓ１と対向する搭載部１４ａと、搭載部１４ａから屈曲して、第１主面Ｓ１に交差する方向に延在する側壁部１４ｃと、を有する。外装体１１は、樹脂注入痕を有し、樹脂注入痕は、側壁部１４ｃと対向する位置にある。【選択図】図１
