PROBLEM TO BE SOLVED: To provide a method of manufacturing a contact point for a vacuum valve, by which the contact point for a vacuum valve having less pores inside and high in density is obtained. SOLUTION: A method of manufacturing a contact point for a vacuum valve comprises: a green compact molding step of molding a green compact; a skeleton forming step of forming a plate-like Cr skeleton 1 by sintering the green compact; a cutting step of forming a sheared surface by cutting the Cr skeleton 1 into two parts along the center of its thickness; a placing step of placing a Cu plate 2 at the center of the sheared surface; and an infiltrating step of infiltrating fused Cu, which is acquired by heating the Cu plate 2, into the Cr skeleton 1.
