Abstract
A method of manufacturing a roll-shaped mold includes: an immersing step of immersing a roll-shaped mold main body into a treatment agent; a first removing step of exposing a portion of the mold main body from a liquid level of the treatment agent in which a central axis of the mold main body is inclined with respect to a horizontal surface; a second removing step in which the mold main body is moved in relation to the liquid level of the treatment agent in which a meniscus is sustained between the exposed portion of the mold main body and the liquid level of the treatment agent and thereby further exposing the mold main body; and a third removing step of removing the entire mold main body from the treatment agent in which the central axis of the mold main body is inclined with respect to the horizontal surface.
