Summary:An optical information recording medium of which the commercial value is not reduced is provided, in which a light reflection layer, an optical recording layer, a first light transmission layer, and a second light transmission layer are provided in this order on one main surface of a disk-shaped substrate, and a method of manufacturing the optical information recording medium is provided. A light reflection layer, an optical recording layer, a protection layer, a first light transmission layer, and a second light transmission layer may be provided in this order on the one main surface of the disk-shaped substrate. The substrate has a first groove and a second groove approximately concentrically formed nearer an inner circumference of the substrate than an area in which the optical recording layer is to be provided. The first light transmission layer is provided such that an edge thereof is situated near an edge of an outer circumferential side of the first groove. The second light transmission layer is provid
