Abstract: A touch sensor film preventing moire occurring in accordance with deformation of a support is manufactured by performing roll transportation of an elongated transparent support 1 having a thickness smaller than 80 μm using a plurality of pass rollers 4, 5, and 6; performing annealing treatment with respect to the support 1 at a temperature which is equal to or lower than a temperature obtained by adding 35° C. to a dynamic glass transition temperature of the support 1; and forming a mesh pattern formed of thin metal wires 8a on a surface of the support 1 subjected to the annealing treatment.

Abstract: An object is to coat a target position on a substrate with a dense film. In order to achieve the object, while a substrate on which a base containing a coating material is formed is transported, an auxiliary agent is applied to the substrate, and then a main agent containing a coating material is applied to the substrate to react the main agent with the auxiliary agent, so that a portion on the substrate where the base is formed is coated with the coating material.
