Abstract: A seating plate pair has a mounting surface having a pair of terminal storage grooves. Distal end portions of a pair of lead terminals are inserted into the pair of terminal storage grooves, respectively. The seating plate includes an auxiliary terminal on the mounting surface. The auxiliary terminal includes an auxiliary mounting portion, and a first embedded portion and a second embedded portion protruding respectively from both sides of the auxiliary mounting portion. 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. On the mounting surface, the auxiliary terminal is disposed away from an adjacent terminal storage groove by ⅕ or more of a width of the adjacent terminal storage groove.

Abstract: An electrolytic capacitor includes a capacitor body and a seating plate having an attachment surface to which the capacitor body is attached. The seating plate has a pair of through-holes into which a pair of lead terminals is inserted, respectively. A mounting surface of the seating plate has a pair of terminal storage grooves and a projection. Distal end portions of the pair of lead terminals inserted into the pair of through-holes, respectively, to be bent along the mounting surface are inserted into the pair of terminal storage grooves, respectively. The projection protrudes from a portion including at least an intermediate portion between the pair of through-holes. The projection includes a narrow portion and wide portions. The narrow portion is positioned between the pair of through-holes. The wide portions are disposed respectively at both sides with respect to the narrow portion in a second axis intersecting a first axis along which the pair of through-holes are arranged. A width of the wide portion in a first axis is larger than a width of the narrow portion in the first axis.

Abstract: An electrolytic capacitor includes a capacitor element; a bottomed case that houses the capacitor element; a sealing member that seals an opening of the bottomed case; a tab terminal connected to the capacitor element and penetrating through the sealing member; and a resin layer that covers at least part of a main surface of the sealing member, the main surface being disposed outside the bottomed case. The tab terminal includes a first portion containing a first metal and a second portion containing a second metal. The resin layer is in contact with the first portion and the second portion. Linear expansion coefficient α1 of the first metal, linear expansion coefficient α2 of the second metal, and linear expansion coefficient αr of the resin layer satisfy a relation of α1
