To provide a film capacitor excellent in reliability.SOLUTION: A film capacitor includes: a film capacitor element that has a first electrode and a second electrode; a first bus bar that has a first connection part and a first terminal part; a second bus bar that has a second connection part and a second terminal part; a box body that opens in one surface; a lid body; and a sealing member. The box body has a groove part in an opening end face, and the lid body has a first surface facing the box body and a second surface on the opposite side of the first surface, has a first through hole and a second through hole, and has a projection on the first surface. The first connection part is inserted into the first through hole to connect the first electrode and the first terminal part on the second surface to each other, and the second connection part is inserted into the second through hole to connect the second electrode and the second terminal part on the second surface to each other. The film capacitor element is suspended inside the box body, and the lid body is fitted to the groove part at the projection and fixed to the box body. The sealing member is located inside the groove part and on the second surface to seal the space between the box body and the lid body, first through hole, and second through hole.SELECTED DRAWING: Figure 1
【課題】 信頼性に優れたフィルムコンデンサを提供する。【解決手段】 フィルムコンデンサは、第1電極と第2電極とを有するフィルムコンデンサ素子、第1接続部と第1端子部とを有する第1バスバー、第2接続部と第2端子部とを有する第2バスバー、一面が開口した箱体、蓋体及び封止部材を含む。箱体は、開口端面に溝部を有し、蓋体は、箱体に対向する第1面、第1面とは反対側の第2面、第1貫通孔及び第2貫通孔を有し、第1面に突条部を有する。第1接続部は、第1貫通孔に挿通され、第1電極と第2面上の第1端子部とを接続し、第2接続部は、第2貫通孔に挿通され、第2電極と第2面上の第2端子部とを接続する。フィルムコンデンサ素子は、箱体内に懸架され、蓋体は、突条部が溝部に嵌合されて、箱体に固定される。封止部材は、溝部内及び第2面上に位置し、箱体と蓋体との間、第1貫通孔及び第2貫通孔を封止する。【選択図】 図1
