1. An antenna substrate comprising:
a substrate including a first main surface and a second main surface; and
a coil including:
a first portion supported on the first main surface; and
a second portion supported on the second main surface,
wherein a single communicating portion is formed in the substrate, the communicating portion communicating the first main surface with the second main surface,
wherein the first portion and the second portion are electrically connected to each other in series, through the communicating portion, and
wherein a winding direction of the first portion and a winding direction of the second portion are identical, when viewed from a direction along a normal line of the first main surface or a normal line of the second main surface.
