An antenna comprising:
- a core material which is formed by laminating a plurality of thin plates made of a magnetic material, both end portions of the core material being widened in a thickness direction;
- and
- a coil which is wound around the core material.
An antenna comprising:
- a core material which is formed by binding a plurality of wire rods made of a magnetic material, both end portions of the core material being widened from a center of a bundle;
- and
- a coil which is wound around the core material.
A method for manufacturing an antenna comprising:
- a first step of placing a spacer at both end portions of a plurality of laminated thin plates that is made of a magnetic material, and further laminating a plurality of thin plates that is made of the magnetic material thereon to form a core material;
- a second step of containing the core material in a pair of upper and lower cases;
- and
- a third step of winding a coil on the cases.
