GASKET MANUFACTURING METHOD

Provided is a gasket manufacturing method, which enables an improvement in sealing performance by making the thickness of a gasket formed on a bead on a base member more uniform. The manufacturing method of a separator-integrated gasket includes a step of dispensing a gasket material, and a step of curing the gasket material dispensed on the bead 111. The bead 111 includes portions having different widths in a short direction thereof. Compared to a moving speed of a dispensing apparatus relative to the separator body 110 in a narrow portion where the width is small, the moving speed is slower in a wide portion having a larger width than the narrow portion.
