Abstract
A glass-shaping mold includes a steel base member, and a crystallized, machined layer, an intermediate layer and a mold-releasing layer which are sequentially formed on the base member. The machined layer is a layer of nickel alloy containing phosphorus. The intermediate layer is a layer formed of chromium, nickel, copper or cobalt. Alternatively, the intermediate layer is a layer of an alloy layer containing at least one of these elements. The mold-releasing layer is a layer of an alloy containing iridium and rhenium.
