1. An electroconductive film comprising:
a substrate;
a first electroconductive pattern disposed on a main surface of the substrate; and
a second electroconductive pattern, wherein
the first electroconductive pattern includes a plurality of first electroconductive lines extending in a first direction along the main surface and a plurality of second electroconductive lines extending along the main surface in a second direction orthogonal to the first direction,
the first electroconductive pattern includes at least
a first mesh portion arranged at an end part of the first electroconductive pattern in the second direction;
a second mesh portion adjacent to the first mesh portion in the second direction; and
a third mesh portion other than the first mesh portion and the second mesh portion,
in the second direction, each of a first pitch of the first mesh portion and a second pitch of the second mesh portion is smaller than a third pitch of the third mesh portion,
a sum of the first pitch and the second pitch is greater than the third pitch, and each of the first pitch and the second pitch is greater than a difference between the sum and the third pitch,
the first mesh portion and the second mesh portion are dissimilar in shape to the third mesh portion, and
the second electroconductive pattern is disposed so as to face the first electroconductive pattern with a space from the first electroconductive pattern in the second direction, and the first electroconductive pattern is electrically insulated from the second electroconductive pattern.
