Electrolytic capacitor and seating plate

A seating plate provided in an electrolytic capacitor, wherein:

• the electrolytic capacitor includes a capacitor body that includes a capacitor element, a container housing the capacitor element, and a pair of lead terminals protruding from a bottom surface of the container, the container having a bottomed cylindrical shape,
• the capacitor body is attached to an attachment surface of the seating plate,
• the seating plate has a pair of through-holes into which the pair of lead terminals are inserted, respectively,
• the seating plate has a mounting surface opposite to the attachment surface, the mounting surface having a pair of terminal storage grooves into which distal end portions of the pair of lead terminals are inserted, respectively, the pair of lead terminals being inserted into the pair of through-holes, respectively, to be bent along the mounting surface,
• the seating plate includes an auxiliary terminal disposed along each of the pair of terminal storage grooves on the mounting surface of the seating plate,
• the auxiliary terminal includes an auxiliary mounting portion, a first embedded portion, and a second embedded portion, the auxiliary mounting portion being disposed along a first axis along which an adjacent terminal storage groove among the pair of terminal storage grooves, the first embedded portion and the second embedded portion protruding respectively from both sides of the auxiliary mounting portion along a second axis intersecting the first axis,
• the first embedded portion and the second embedded portion are embedded in the seating plate, and the auxiliary mounting portion is exposed on the mounting surface of the seating plate, and
• on the mounting surface of the seating plate, the auxiliary terminal is disposed away from the adjacent terminal storage groove among the pair of terminal storage grooves by ⅕ or more of a width of the adjacent terminal storage groove.
