CAPACITANCE TYPE TOUCH SENSOR, ELECTRONIC DEVICE, AND METHOD OF MANUFACTURING TRANSPARENT CONDUCTIVE-FILM LAMINATE

WIPO Patent Application WO/2011/078231

A1

Provided is a capacitance type touch sensor, wherein an adhesion layer can be prevented from being whitened by steam, while preventing deterioration in optical characteristics. A transparent base material sheet (312), a transparent conductive-film layer (313), and a transparent adhesion layer (314) are formed on a protection sheet (311). The adhesion layer (314) is formed upon the transparent conductive-film layer (313), so as to cover the transparent conductive-film layer (313). The protection sheet (311) has a steam transmittance of not more than 1g/(m2•day•atm), and has an in-plane direction retardation value at a wavelength of 550 nm to be not more than 20 nm. The base material sheet (312) has an in-plane direction retardation value at a wavelength of 550 nm to be not more than 20 nm.
