Abstract
There is provided a non-contact communication antenna including a first antenna pattern that is formed on one surface of a base material, and a second antenna pattern that is formed on a back surface of the one surface of the base material. The first antenna pattern includes a first coil section and a first electrode section. The second antenna pattern includes a second coil section and a second electrode section. Capacitance of the first electrode section and the second electrode section compensates a change in capacitance depending on a formation situation of the first coil section and the second coil section.
