Abstract: A first electroconductive pattern includes a plurality of first electroconductive lines extending in a first direction along a main surface and a plurality of second electroconductive lines extending along the main surface in a second direction orthogonal to the first 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 in a case where a difference between the sum and the third pitch is assumed to be a fourth pitch, each of the first pitch and the second pitch is greater than the fourth pitch, and the first mesh portion and the second mesh portion are dissimilar in shape to the third mesh portion.

Abstract: An antenna includes a radiation conductor having a circular shape, a feed line configured to feed power to the radiation conductor, and a terminal connected to the feed line, in which impedance of the feed line is greater than impedance of a feed point of the terminal, and a line length of the feed line is longer than a radius of the radiation conductor.

Abstract: An electroconductive pattern includes a third mesh portion that does not 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.
