To provide a capacitor which can ensure insulation between an electrode surface of a capacitor element and a bus bar, and also allows positioning and lifting prevention of the capacitor element, without using a separate insulation member.SOLUTION: A capacitor comprises: a case 5; a capacitor element 2 which has a first electrode surface 21 facing a case opening part 53 side and a second electrode surface 22 facing a case bottom part 51 side; a first bus bar 3 connected to the first electrode surface 21; a second bus bar 4 connected to the second electrode surface 22; and filling 6. The case 5 has a protrusion 54 which extends from the bottom part 51 and a lateral wall part 52 so as to define a gap G between itself and an inner surface of the lateral wall part 52. The second bus bar 4 has an erect surface part 41b which extends along a lateral surface 24 of the capacitor element 2 to the opening part 53 side of the case 5. With the erect surface part 41b inserted into the gap G between the protrusion 54 and the lateral wall part 52, the protrusion 54 is interposed between the first electrode surface 21 and the erect surface part 41b.SELECTED DRAWING: Figure 3 【課題】別体の絶縁部材を用いることなく、コンデンサ素子の電極面とバスバーとの絶縁の確保と、コンデンサ素子の位置決め及び浮き上がりの防止とを達成できるコンデンサを提供する。【解決手段】ケース５と、第１電極面２１をケース開口部５３側に向け、第２電極面２２をケース底部５１側に向けるコンデンサ素子２と、第１電極面２１に接続される第１バスバー３と、第２電極面２２に接続される第２バスバー４と、充填物６とを備え、ケース５が、底部５１及び側壁部５２から延びて側壁部５２の内面との間に隙間Ｇを形成する突起５４を有し、第２バスバー４が、コンデンサ素子２の側面２４に沿ってケース５の開口部５３側に延びる立面部４１ｂを備え、立面部４１ｂが、突起５４と側壁部５２との間の隙間Ｇに差し込まれることで、第１電極面２１と立面部４１ｂとの間に突起５４が介在している。【選択図】図３
