1. An antenna device comprising:
a first conductor corresponding to communication in a first frequency band;
a ground conductor that faces the first conductor; and
a second conductor that is disposed between the first conductor and the ground conductor, faces the first conductor and the ground conductor, and has a power supply point,
wherein the second conductor is disposed so as to face one end side of the first conductor in an upper-lower direction of the first conductor,
wherein the first conductor has a slot disposed at a position facing another end side opposite to the second conductor, the slot corresponding to communication in a second frequency band that is different from the first frequency band,
wherein the slot has a length equal to or less than ½ of a wavelength corresponding to the second frequency band in a direction parallel to a long-side direction of the first conductor, and
wherein the first conductor has a length equal to or less than ½ of a wavelength corresponding to the first frequency band in the direction parallel to the long-side direction of the first conductor.
