Abstract
Provided is an optical recording medium capable of suppressing sticking between the optical recording mediums in a case where a plurality of optical recording mediums are superimposed on each other. The optical recording medium includes an optical recording medium main body having a first surface and a second surface, and a first convex structure layer provided on the first surface. The first convex structure layer has a surface provided with a plurality of first convexities, and includes first particles and a first resin material. The plurality of first convexities are formed by a part of the first particles included in the first convex structure layer, the part of the first particles protruding from the surface of the first convex structure layer.
