Patent ID: 8256684

Claim:
An antenna apparatus for use in a non-contact type IC card into and from which data can be written or read by an electronic apparatus having a communication function, by virtue of inductive coupling, the antenna apparatus comprising: a loop coil produced by winding a conductive wire in a plane and configured to perform the inductive coupling; and a magnetic member covering one surface region of one side of the loop coil, passing through the loop coil, and covering the other region of the other side of the loop coil, wherein the magnetic member has a first part covering one surface region of one side of the loop coil, a second part covering the other surface region of the loop coil, and an insertion part passing through an insertion hole made in the loop coil, coupling the first part and the second part and having a smaller width than the first and second parts, and the one surface of the loop coil, which is not covered with the magnetic member, is a region for communication with the electronic apparatus, wherein a first width of the first part and a second width of the second part are larger than the loop coil.
