<P>PROBLEM TO BE SOLVED: To provide an RFID antenna which has enhanced characteristics of an antenna coil part such as Q value and inductance L value. <P>SOLUTION: In a mobile terminal 10, for example, which exchanges signals with a reader/writer contactlessly, a cable layer 23 in which a plurality of lead wires 21a-21d are aligned at predetermined intervals and fixed by a resin 22, is adhered and fixed to a magnetic sheet 24 made of a magnetic material by an adhesive 25, for example, to configure an antenna coil part 2. The antenna coil part 2 is disposed along an outer wall 1 of a battery pack, folded portions 2<SB>A1</SB>, 2<SB>A2</SB>to which a radius of curvature ≥0.2R is applied, are formed at an end of the antenna coil part 2, and distal ends thereof are connected to a connector contact. <P>COPYRIGHT: (C)2008,JPO&INPIT |
