A recording layer included in an optical information recording medium of the present invention includes: a mixture of a low oxide Te-O-M (M denotes at least one element selected from the group consisting of a metallic element, a metalloid element, and a semiconductor element) or a low oxide A-O (A denotes at least one element selected from the group consisting of Sb, Sn, In, Zn, Mo and W; and a material X (X denotes at least one compound selected from the group consisting of a fluoride, a carbide, a nitride and an oxide). Herein the low oxide refers to an oxide whose composition ratio of oxygen element is smaller than a composition ratio of oxygen element according to a stoichiometric composition.
