A separator for a fuel battery, where gasket is formed integrally with a separator body by forming rubber in gasket forming grooves provided in the separator body. When rubber is formed in the grooves, damage to the grooves can be constrained, and this prevents lowering of sealing ability caused by damage to the separator. The width of a gasket forming groove formed in one surface of the separator body is greater than a gasket forming groove formed in the other surface. Groove side-surfaces in a gasket forming groove has an inclined shape or a curvature is provided on square corners of groove bottom surfaces. |
