There is provided an optical recording medium formed based on a drastically new concept of forming a phase-change recording layer by using other elements than chalcogen. The optical recording medium (1) has a phase-change recording layer (5) thereof formed such that a reversible phase change of the phase-change recording layer (5) between an amorphous phase and a crystalline phase can be utilized. The phase-change recording layer (5) contains Sb as a main component and at least one element selected from the groups consisting of elements of other groups than group VIb and rare earth metal elements, as a sub-component, as e.g. Mn, Ge, In or Ag.
