Abstract
This invention provides an antenna apparatus () for use in a non-contact type IC card into and from which data can be written and read by electronic apparatuses having a communication function, by virtue of inductive coupling. The antenna apparatus comprises a loop coil () and a magnetic member (). The loop coil is produced by winding a conductive wire in a plane and configured to perform the inductive coupling. The magnetic member covers one region () of the loop coil, provided at one side, from one surface of the loop coil, passes through the loop coil, and covers the other region () of the loop coil, provided at the other side, from the other surface of the loop coil. The entire region of the loop coil is thus covered.
