Narrow-frame touch panel

An analog resistive-film type thin-frame touch panel, comprising:

• a lower-side electrode member having a lower-side transparent electrode on a part of a top face of a lower-side transparent insulating base member, a pair of lower-side bus bars disposed on two parallel sides of the lower-side transparent electrode, and lower-side external terminal connection portions disposed on a portion other than the lower-side transparent electrode and connected to the lower-side bus bars;
• and
• an upper-side electrode member having an upper-side transparent electrode on a part of a bottom face of an upper-side transparent insulating base member having flexibility, a pair of upper-side bus bars disposed on two parallel sides of the upper-side transparent electrode, and upper-side external terminal connection portions disposed on a portion other than the upper-side transparent electrode and connected to the upper-side bus bars,
• the lower-side electrode member and the upper-side electrode member being disposed facing each other via an insulative spacer in such a way that the upper-side bus bars and the lower-side bus bars are arranged in a square pattern, and being bonded at peripheral portions, wherein the lower-side bus bars are formed by metal thin wires having a circular cross section and a wire diameter of 30 to 100 μm while the upper-side bus bars are formed by metal thin wires having a circular cross section and a wire diameter of 30 to 100 μm, and in each of the upper-side electrode member and the lower-side electrode member, the metal thin wires are respectively fixed onto the upper-side transparent insulating base member and the lower-side transparent insulating base member through a conductive past.
