WIPO Patent Application WO/2023/195526

A1

An electrolytic capacitor lead terminal 1 comprises a rolled part 12, a rod-shaped part 18, and a lead wire 20. A side peripheral surface of the rolled part has: a first main surface 14a and a second main surface 14b; a pair of sheared surfaces 14c, 14d; a first connection surface connecting the first main surface and the sheared surfaces; and a second connection surface connecting the second main surface and the sheared surfaces. One of the first connection surface and the second connection surface has a drooping surface on one side thereof, and the other of the first connection surface and the second connection surface includes a pressed surface continuous to the main surface, from among the first main surface and the second main surface, to which the connection surface itself is connected. In a cross-sectional view, the drooping surface and the pressed surface are both approximately arc-shaped, and a step extending in the axial direction is provided to each one of the pair of sheared surfaces, the step being positioned at a position separated from the center in the thickness direction of the rolled part.
