Gasket and fuel cell

A gasket arranged between an end plate arranged at an end of a cell stack of a fuel cell in a cell stacking direction and a case covering a periphery of the cell stack, wherein

• the gasket is configured to seal a gap between the end plate and the gasket and a gap between the case and the gasket,
• the gasket comprises:
• a base plate that extends along opposed surfaces of the end plate and the case at a position between the end plate and the case;
• and
• an elastic material layer arranged on and along a surface of the base plate to be located between the base plate and the end plate,
• the base plate includes
• an inner peripheral section located close to an inner side of the case,
• an outer peripheral section located close to an outer side of the case, and
• a slope section located between the inner peripheral section and the outer peripheral section to connect the inner peripheral section and the outer peripheral section to each other,
• the inner peripheral section and the outer peripheral section are located at different positions in a thickness direction of the base plate, and
• the slope section is inclined with respect to the inner peripheral section and the outer peripheral section.
