Abstract
A loop antenna includes: a substrate; a first conductor which is provided on a first surface of the substrate, is conductive and is grounded; a second conductor which is formed as a loop to surround the substrate along a surface orthogonal to the first surface, is conductive, is fed on a second surface of the substrate, which is opposite to the first surface, and is electrically connected to the first conductor; and a third conductor which is provided on at least one side surface of the substrate, which intersects the surface on which the second conductor is formed as a loop, is conductive and is electrically connected to the first conductor.
