A conductive sheet includes a transparent substrate and a plurality of thin metal wires formed in a mesh shape on one surface of the transparent substrate. The plurality of thin metal wires includes an n-sided polygon formed in a virtual pattern and an inverted virtual pattern and six connecting lines. The virtual pattern and the inverted virtual pattern obtained by flipping the virtual pattern horizontally are densely laid such that intersection points disposed on respective sides of the virtual pattern and the inverted virtual pattern are overlapped with each other and that opening regions formed by the plurality of thin metal wires are aperiodically arranged.

Conductive sheet, touch sensor, and method for manufacturing touch sensor

A touch panel includes: first electrodes disposed in parallel at a position corresponding to a viewing area of a panel member and have a capacitance changing according to a proximity of an object to be detected; second electrodes that intersect with the first electrodes, are disposed in parallel, and similarly change in capacitance; third electrodes disposed in parallel between the first or second electrodes and have electrical resistances changing according to posture and temperature; and fourth electrodes extending along the respective third electrodes and similarly change in electrical resistance. A resistance change rate of the fourth electrodes due to temperature is the same as for the third electrodes. The resistance change rate of the fourth electrodes due to the posture change is 90% or less than for the third electrodes due to the posture change. This allows a pressing force to be accurately measured.

Touch panel

[Object] In a touch screen in which an electrode portion is formed on a base film, a pattern of the electrode portion is made less visible. [Solution] A touch screenincludes a first base film, a first transparent electrode, a second base film, a second transparent electrode, and a second intermediate base film. The first transparent electrodeis formed on the first base film. The second base filmis placed to face the first base film. The second transparent electrodeis formed on the second base film. The second intermediate base filmhas a retardation value of 3000 nm or more and is placed so that a contraction direction thereof and contraction directions of the first base filmand the second base filmare matched.
