PROBLEM TO BE SOLVED: To provide an antenna device capable of further spreading directivity.SOLUTION: An antenna device 1 includes: a support body 10 having a curved surface; an extensible sheet 11 provided along a curved surface of the support body 10; and an antenna coil 12 provided on a surface of the extensible sheet 11. The antenna coil 12 is formed on a main surface of the extensible sheet 11 as a plane pattern. Then, the extensible sheet 11 is applied to the support body 10 thereby making the antenna coil 12 into a three-dimensional pattern along the curved surface of the support body 10. |
