Abstract

A coil-type antenna device includes a plate-like magnetic member; a coil formed by winding a conductor wire around a plate-like magnetic member; and a fixing structure configured to fix the conductor wire to the magnetic member.

Claims

1. A coil-type antenna device comprising:

a plate-like magnetic member;

a coil formed by winding a conductor wire around a plate-like magnetic member; and

a fixing structure configured to fix the conductor wire to the magnetic member.

2. The coil-type antenna device according to claim 1, wherein the magnetic member includes the fixing structure.

3. The coil-type antenna device according to claim 2, wherein the fixing structure includes a groove which is provided in the magnetic member and in which the conductor wire is fit.

4. The coil-type antenna device according to claim 1, wherein the fixing structure includes an adherent layer interposed between the magnetic member and the conductor wire.

5. The coil-type antenna device according to claim 1, wherein the fixing structure includes a pressure-bonding member that is heat-and-pressure bonded to the coil.

6. The coil-type antenna device according to claim 1, wherein the fixing structure includes an adhesive applied to the conductor wire to adhere to the magnetic member.
