PROBLEM TO BE SOLVED: To easily provide a non-contact data transmitter/receiver in which the capacitance of an antenna is increased and adjusted without newly designing the antenna. SOLUTION: This antenna is provided with a capacitance control means 3 composed of a plurality of antenna side planar conductors 7 individually and integrally connected to the antenna 6 and arranged with intervals in the loop length direction of the antenna 6 and a plurality of opposite side planar conductors 8 of mutually non-connected independent patterns respectively arranged corresponding to the antenna side planar conductors 7 through an insulating material A. |
