Abstract:
Provided are a transparent electrode-attached complex which includes a base material, a transparent electrode pattern, an optical adjustment member, and a transparent protective layer in this order, in which the optical adjustment member has at least one layer of low-refractive index layers that are odd-numbered layers from a transparent electrode pattern side and at least one layer of high-refractive index layers that are even-numbered layers from the transparent electrode pattern side, a difference in refractive index between the low-refractive index layer and the high-refractive index layer that are directly adjacent to each other is 0.05 or more, a refractive index of the high-refractive index layer is 2.10 or lower, and a thickness of each of the low-refractive index layer and the high-refractive index layer is 5 to 80 nm, has excellent transparent electrode pattern-masking properties, is capable of reducing unevenness attributed to an optical adjustment member, and has an excellent pencil hardness even without using a transparent film having a high refractive index on the base material-side of a transparent electrode pattern; a transfer film; a method for manufacturing a transparent electrode-attached complex; and an electrostatic capacitance-type input device.
