A method for manufacturing an optical recording medium is provided, which can suppress the amount of eccentricity of a central hole to be small and can form a light transmitting layer with a uniform thickness even in a region around the central hole. In this manufacturing method, a manufacturing hole having a smaller inner diameter than that of the central hole is formed in a substrate. A core member is fitted into the manufacturing hole to be in close contact with the inner circumference of the manufacturing hole. A light transmitting layer is spread over an information recording surface of the substrate by supplying radiation curable resin in a region around the core member and rotating the substrate. Then, the light transmitting layer is cured by irradiation of radiation, and the core member is removed from the manufacturing hole. Thereafter the central hole is formed.
