The purpose of the present invention is to use chalcogenide glass to produce an infrared transmitting glass that is more suitable for mold-forming than the conventional glasses. Specifically, the invention provides an infrared transmitting glass for mold forming which contains, in molar concentrations, 2-22% of Ge, 6-34% of at least one element selected from the group consisting of Sb and Bi, 1-20% of at least one element selected from the group consisting of Sn and Zn and 58-70% of at least one element chosen from the group comprising S, Se and Te.
