PURPOSE:To provide an optical information recording medium excellent in moisture resistance and in long-term preservability by preventing the deterioration of a recording layer caused by oxygen incorporated in moisture which intrudes from an interrupted part or the like of an adhesive layer. CONSTITUTION:A specific metallic power is incorporated in the adhesive layer between inner, outer circumferential spacers and a substrate and in inner, outer circumferential spacers in the optical information recording medium having air sandwich structure. Since the metallic powder is combined with oxygen in intruding moisture to form an oxide, the influence to the recording layer is prevented. |
