Abstract: An input device having a row electrode and a column electrode made by patterning a meshed metallic layer by forming a dividing section on a metallic line constituting the meshed metallic layer can make areas of individual dividing sections of the metallic lines uniform, whereby uneven shading due to the patterned, meshed conductive layer is suppressed from appearing on a touch operation surface. In the input device having the row electrode and the column electrode made by patterning the meshed metallic layer by forming the dividing section on the metallic line constituting the meshed metallic layer, at an intersecting section where metallic lines Mw2 constituting a meshed conductive layer Lp2 intersects an ideal contour Sp2 of a meshed column electrode, the direction for dividing the metallic lines at the intersecting section is set to the direction matching the direction of width of the metallic lines such that the area of the dividing section traversing the metallic line is minimal.
