PROBLEM TO BE SOLVED: To provide a manufacturing method of a gasket having low hardness of a rubber part, superior in sealing performance, and improved so that moisture and gas do not pass through the rubber part. SOLUTION: This manufacturing method of the gasket for precision mechanical equipment is characterized by covering a rubber material by forming a coating film of a resin material on a surface of the hardened rubber material by hardening the rubber material in prescribed hardness by irradiating an active energy line to the stuck rubber material after sticking the liquid rubber material hardening by irradiation of the active energy line to a prescribed position of a sealing surface, and can thereby obtain the gasket having high follow-up performance to a shape of a mating member being a sealing object, superior in the sealing performance, having barrier performance to the moisture and the gas in a part of the hardened rubber material, holding high sealing performance, and capable of maintaining the function of the precision mechanical equipment over a long period.
