PROBLEM TO BE SOLVED: To provide a production method of a contact material for vacuum valve in which adhesion is enhanced by preventing a clearance from occurring to the bonding surface of the contact material and a base metal.SOLUTION: In the production method of a contact material for vacuum valve where a disc-like base metal 2 being brazed to an electrode rod and a contact member 1 provided on the bonding surface 2b on the reverse side of the brazing surface 2a of the base metal 2 are formed integrally by sintering, a tapered surface is formed in the outer peripheral side surface 2c of the base metal 2 so that the external-diameter on the brazing surface 2a side becomes smaller than that of the bonding surface 2b side. The bonding surface 2b and the outer peripheral side surface 2c of the base metal 2 are covered with a mixed material of a plurality of kinds of metal powder composing the contact member 1 and stamped, and then the base metal 2 and the contact member 1 are brought into tight contact and integrated.
