<p>An antenna (1) has a flexible sheet (10), a first coil electrode (21) is formed on the first main surface (12) of the flexible sheet (10), and a second coil electrode (31) is formed on the second main surface (13). The first coil electrode (21) and the second coil electrode (31) are formed by being wound in the reverse directions when viewed from different directions. One end portion (22A) of the first coil electrode (21) and one end portion (32A) of the second coil electrode (31) are formed so as to face each other with the flexible sheet (10) therebetween, and the other end portion (22B) of the first coil electrode (21) and the other end portion (32B) of the second coil electrode (31) are also formed to face each other with the flexible sheet (10) therebetween. Thus, a resonant antenna (1) is configured by having the first coil electrode (21) and the second coil electrode (31) as inductors, forming a capacitor with the end portions (22A, 32A) and forming a capacitor with the end portions (22B, 32B).</p> |
