Claim 7:
8. An antenna module comprising:
an antenna substrate on which an antenna is formed;
a high-frequency integrated circuit that processes high-frequency signals: and
a substrate in which a through-hole is formed from a first surface to a second surface which is a surface opposite to the first surface, the substrate comprising:

two first through-holes to which the high-frequency signals are transmitted and which are arranged side by side so as to have a predetermined distance; and
at least three reference potential second through-holes arranged side by side so as to have an distance smaller than the predetermined distance with respect to the two first through-holes, wherein
among three of the second through-holes, one of the second through-holes is arranged in a region between the two first through-holes, and
other two of the second through-holes are arranged in a region other than the region between the first through-holes such that
one of the other two second through-holes is arranged side by side with respect to one of the two first through-holes, and
the other of the other two second through-holes is arranged side by side with respect to the other of the two first through-holes, and

wherein the antenna substrate and the high-frequency integrated circuit are mounted on the first surface and the second surface of the substrate respectively so that at least a portion of the antenna substrate and the high-frequency integrated circuit overlap each other in a plan view, and the antenna substrate and the high-frequency integrated circuit are electrically connected through the first through-hole.
