Abstract
A high-precision marker, which is easy to manufacture, has a base material layer, a first layer which is laminated onto one surface of the base material layer, and which is observed in a first color, and a second layer which is partially laminated onto the first layer, is observed in a second color different from the first color, and partially conceals the first layer, wherein the first layer is observable in a region in which the second layer is not laminated, and the second layer is formed by a resist material.
