Disclosed is a binder composition for use in mold manufacturing whereby mold strength degradation in high-humidity environments can be prevented, as can the production of irritant gases during casting. Also disclosed is a composition, using the aforementioned binder composition, for use in molds. The disclosed binder composition contains a furan resin and at least one metal compound containing at least one metallic element selected from among groups 2, 4, 7, 10, 11, and 13 of the periodic table. Said metallic element(s) constitute between 0.01% and 0.70% of the weight of the binder composition.
