Abstract
An antenna pattern includes a base material, and a dipole antenna formed in a band shape, made of a conductive material on a front surface of the base material, and extending linearly. The dipole antenna has a connection portion positioned in the middle of the dipole antenna in a longitudinal direction, and to which an IC chip is connected. A pair of long sides of the dipole antenna positioned at both ends of the dipole antenna in a width direction and extending in the longitudinal direction of the dipole antenna are formed in waveform shapes in which a plurality of concave and convex shapes are arranged in the longitudinal direction.
