Abstract: An inspection method of a mold with a liquid repellent layer formed on a side surface of a mesa portion protruding from a base material, including obtaining information indicating a relationship between a measurement result acquired by measuring the liquid repellent layer in a non-contact manner and a state of the liquid repellent layer, measuring the liquid repellent layer formed on the side surface in a non-contact manner, and obtaining a state of the liquid repellent layer formed on the side surface based on the information obtained in the obtaining the information and a measurement result acquired in the measuring.

Abstract: Provided is a transparent member having formed thereon a film having high reliability, the film being capable of suppressing an increase in its haze and maintaining its hydrophilicity for a long time period even when exposed to an outdoor environment. The transparent member is a transparent member including a resin base material and a porous layer arranged thereon, wherein the porous layer has a network structure in which silica particles are joined to each other with a binder, wherein the resin base material has a mixed layer that the network structure has entered, wherein the mixed layer has a thickness of 20 nm or more and 160 nm or less, and wherein a thickness variation in a range having a length of 1 ?m of a section of the mixed layer in its thickness direction along the surface of the resin base material is 15% or less.

Abstract: A removing method that makes it possible to remove a residual generated at least near a side surface of a convex portion of a mold. The removing method is a removing method of removing a residual attached to a mold which includes a base having a main surface and a convex portion provided on the main surface and in which a concavo-convex pattern formed on an upper surface of the convex portion is pressed against a curable composition, the removing method includes removing the residual, and the removing of the residual includes removing the residual by dissolving a liquid-repellent layer formed on at least a side surface of the convex portion with a predetermined solvent.
