Abstract
To provide a separator for a fuel battery in which a gasket is integrally formed with rubber in gasket forming grooves provided in a separator main body without the gasket forming grooves being damaged at a time of forming with the rubber and sealing performance being lowered due to the damage of the separator, the separator for the fuel battery is structured such that a groove width of the gasket forming groove formed in one surface of the separator main body is made larger than a groove width of the gasket forming groove formed in the other surface, or groove side surfaces in the gasket forming groove are formed in an inclined shape, or a curvature is provided in corner portions of a groove bottom surface.
