PROBLEM TO BE SOLVED: To provide a mold for molding a gasket which allows downsizing of the manufacturing equipment by reducing minimally the plane shape of the mold for integrated molding of a large gasket, requires no excess trouble or time for manufacture owing to the integrated molding and does not cause occurrence of poor strength in connecting parts. SOLUTION: The mold 1 is used to mold a gasket in an endless form and has two or more molding sections 11 and 21 in which two molding grooves 12 and 22 are arranged spirally in parallel. The spiral molding grooves 12 and 22 have reversed portions 14 and 24, respectively, at their inner ends 13 and 23, and their outer ends 15 and 25 are connected in series.
