PROBLEM TO BE SOLVED: To realize a precise processing by avoiding the deterioration of the surface roughness of a release layer during molding. SOLUTION: The glass forming mold 5 is provided with a substrate 1 made of steel, a crystallized cutting layer 2 successively formed on the substrate 1, an intermediate layer 3 and a release layer 4, and the cutting layer 2 is a phosphorus-containing nickel alloy layer, and the intermediate layer 3 is a layer consisting of either one of chromium, nickel, copper and cobalt or an alloy layer containing at least one or more kinds of these elements, and further, the release layer 4 is an alloy layer containing iridium and rhenium.
