<P>PROBLEM TO BE SOLVED: To provide an antenna device and a portable terminal which extend communicable regions and have good communication performance in the communicable regions. <P>SOLUTION: An antenna device includes: an insulation antenna substrate 2; an antenna pattern 3 formed on the antenna substrate 2; a magnetic material sheet 4 having a surface larger than the antenna pattern 3; a cutout part 8 overlapping with an opening of the antenna pattern 3; and a metal body 7 having a surface overlapping with a conductor wire of the antenna pattern 3. The cutout part 8 of the metal body 7 connects with an outer peripheral end of the metal body 7, and the metal body 7, the antenna substrate 2, the antenna pattern 3, and the magnetic material sheet 4 are disposed in this written order when viewed from the communication side of the antenna pattern 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
