Abstract
An antenna substrate includes 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. A communicating portion is formed in the substrate. The communicating portion communicates the first main surface with the second main surface. The first portion and the second portion are electrically connected to each other, through the communicating portion. 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.
