WIPO Patent Application WO/2023/140107
Kind Code:
A1
Abstract:
This electrolytic capacitor comprises: a winding part; a positive electrode lead member; and a negative electrode lead member. The winding part includes a wound positive electrode foil and negatived electrode foil. The positive electrode lead member is connected to the positive electrode foil and extends in a first direction. The negatived electrode lead member is connected to the negatived electrode foil and extends in the first direction. When viewed from the first direction, the winding part has a shape including: a first peripheral portion and a second peripheral portion that oppose each other in a second direction that crosses the first direction; and a third peripheral portion and a fourth peripheral portion that oppose each other in a third direction that crosses the first direction and the second direction. A dimension of the winding part in the third direction is greater than a dimension of the winding part in the second direction. When viewed from the first direction, the positive electrode lead member and the negative electrode lead member are disposed so as to have point symmetry with respect to the center of the winding part.
