An end plate of a fuel cell stack includes a metal plate body including a plurality of through holes and a resin cover that covers a wall surface defining each of the through holes. The cover includes a body, a flange projecting outward in a radial direction from an outer end of the body, an annular rim extending toward the inner side from an outer edge of the flange, and a coupling rib that couples an inner circumferential surface of the rim to an outer circumferential surface of the body. The plate body further includes an outer end surface including a recess. The recess is filled with the flange, the rim, and the coupling rib.
