PROBLEM TO BE SOLVED: To miniaturize an antenna that reduces resistance while increasing the value of inductance.SOLUTION: An antenna is provided that is formed in the following manner: on a first plane, first conductors with first width are arranged in whorls such that the distance between the conductors is second width, and on a second plane parallel to the first plane, second conductors with the first width are arranged in whorls such that the distance between the conductors is the second width, and the inside of the whorls of the first conductor and the inside of the whorls of the second conductor are connected by a conductor. In the antenna, a direction from the outside to the inside of the whorls of the first conductor and a direction from the inside to the outside of the whorls of the second conductor accord when viewed from one direction, the first width is larger than the second width, and at least partially the first conductor and the second conductor are arranged alternately when viewed in a radius direction from an axis of the whorls of the first conductor or the whorls of the second conductor. |
