1. An electroconductive film comprising: a film-like substrate; and a mesh-like electroconductive pattern disposed on a main surface of the substrate, wherein
the electroconductive pattern includes a plurality of first electroconductive lines and a plurality of second electroconductive lines configured to extend along the main surface and intersect each other, and to be inclined with respect to an end electroconductive line constituting an end part of the electroconductive pattern,
the electroconductive pattern includes at least
a first mesh portion including the end electroconductive line;
a second mesh portion adjacent to the first mesh portion; and
a third mesh portion configured to have a polygonal shape different from that of each of the first mesh portion and the second mesh portion and not to include the end electroconductive line as one side constituting the mesh portion, and
in a case where a triangular virtual mesh portion including a portion extended from one electroconductive line of the first electroconductive line and of the second electroconductive line which constitute the third mesh portion to the end electroconductive line, a virtual line assuming that another electroconductive line is extended to the end electroconductive line, and the end electroconductive line is set,
a length of a common electroconductive line between the first mesh portion and the third mesh portion is longer than the virtual line of the virtual mesh portion, and
each of an opening area of the first mesh portion and an opening area of the second mesh portion is larger than an opening area of the virtual mesh portion.
