Abstract: A transparent conductive film includes a mesh-shaped portion that is formed of a plurality of conductive wirings, in which the mesh-shaped portion includes a plurality of non-conductive portions (22) that are trimmed by the continuous conductive wiring (21A), the non-conductive portion (22) includes a pair of extension portions (E1, E2) that extend along a pair of central axes (C1, C2) orthogonal to each other and have the same length, the pair of extension portions (E1, E2) intersect each other at an intersection (K) of the pair of central axes (C1, C2), each of the pair of extension portions (E1, E2) includes a projection portion (G1, G2) that projects in a direction intersecting an extension direction, and the non-conductive portion (22) has a shape that is symmetric with respect to each of the pair of central axes. (C1, C2).
