摘要： There is provided a stamper on which stamper-side concave/convex patterns are formed and which is capable of manufacturing an information recording medium on which at least servo patterns are formed by concave/convex patterns. First convex parts that are continuously formed along a direction corresponding to a radial direction of the information recording medium are formed in the stamper-side concave/convex patterns. Each of the first convex parts is formed so that a height of a part of the first convex part from a reference plane, which is set between a front surface and a rear surface of the stamper, to protruding end of the first convex part increases as a length of the part of the first convex part in a direction corresponding to a circumferential direction of the information recording medium increases.
