A fuel cell separator includes a separator main body having a first surface and a second surface, and a first seal member disposed on the first surface. When a region on the first surface of the separator main body corresponding to an electrode member disposed on the second surface is defined as a power generation region, and a region on the first surface of the separator main body corresponding to an in-cell seal member is defined as a seal region, a displacement/vibration reducing member made of polymer is disposed at a part of the seal region. The displacement/vibration reducing member includes multiple protrusions and a coupling portion. When viewed in plan view, an axis line connecting the centers of the figures of the adjacent protrusions does not coincide with a center line passing through the widthwise center of the coupling portion. The coupling portion has a gate cut mark.
