Abstract
External connection terminals in a conductive film and circuit-side terminals in a flexible circuit are respectively arranged in a first direction and are disposed through an anisotropic conductive membrane so as to at least partially overlap each other, the conductive film has detection electrodes and lead wires respectively connecting the detection electrodes to the external connection terminals, at least two external connection terminals have connection portions with the lead wires disposed at different locations, and, in each external connection terminal, an overlapping region between the circuit-side terminal and the anisotropic conductive membrane has ends in a second direction orthogonal to the first direction, and a width W1 of a first end in the first direction being located on a connection portion side between the external connection terminal and the lead wire is smaller than a width W2 in the first direction of the external connection terminal overlapping the first end.
