Abstract: An antenna element is provided with a substrate made of a dielectric body, first to third terminal electrodes formed on a bottom surface of the substrate, a helical coil pattern that is formed in the inside of the substrate, a first lead pattern connected to one end of the helical coil pattern or near the one end, a second lead pattern connected to the other end of the helical coil pattern or near the other end, a first through-hole conductor that connects the first terminal electrode and the first lead pattern, a second through-hole conductor that connects the second terminal electrode and the second lead pattern, and a third through-hole conductor that connects the third terminal electrode and the one end of the helical coil pattern.
