Patent ID: 7499038

Claim:
An analog resistive-film type thin-frame touch panel, comprising: a lower-side electrode member having a lower-side transparent insulating base member, a lower-side transparent electrode on a part of a top face of the 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; an upper-side electrode member having a flexible upper-side transparent insulating base member, an upper-side transparent electrode on a part of a bottom face of the flexible upper-side transparent insulating base member, 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; and an insulative spacer, wherein the lower-side electrode member and the upper-side electrode member are disposed facing each other via the insulative spacers such that the upper-side bus bars and the lower-side bus bars are arranged in a square pattern, and the lower-side electrode member and the upper-side electrode member are bonded at peripheral portions, 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, 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 the metal thin wires and a portion of each of the upper-side and lower-side transparent insulating base members around the metal thin wires are covered with a conductive paste so that the metal thin wires are respectively fixed onto the upper-side transparent insulating base member and the lower-side transparent insulating base member.
