PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical disk for forming quickly and easily a light transmission layer whose thickness is uniform, and to provide an optical disk device thereof. SOLUTION: In the method for manufacturing the optical disk for forming a light transmission layer on an information recording surface 4A on an optical disk substrate 2 in a uniform thickness, the formation of the light transmission layer comprises a process for rotating a rotary table, dropping an ultraviolet curing resin onto the information recording surface, and covering the entire information recording surface with the ultraviolet curing resin after fixing the optical disk substrate onto the rotary table 32 with the information recording surface facing up; a process for rotating the rotary table and measuring the thickness of the ultraviolet curing resin; a process for successively performing work for applying ultraviolet rays from the inner periphery side to the outer periphery side and primarily curing the ultraviolet curing resin for temporary curing, when the measurement result of the thickness of the ultraviolet curing resin reaches a predetermined, prescribed thickness; and a process for applying ultraviolet rays having intensity that is stronger than that in primary curing onto the entire surface of the ultraviolet curing resin for complete curing, after the rotary table stops rotating.
