Manufacturing method of touch sensor film
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 8 a on a surface of the support 1 subjected to the annealing treatment.
