1. A radio IC device comprising:
- a flexible dielectric base including a first surface, a second surface, and an end surfaces, the first surface and the second surface facing each other and being connected to one another by the end surface;
a radiation element including a metal film or a metal foil wrapped around the dielectric base and extending from the first surface to the second surface through the end surface; and
a radio IC element mounted on the radiation element;
whereinthe radiation element includes, in a portion of the radiation element other than a portion of the radiation element on which the radio IC element is mounted, a bonded portion that is bonded to the dielectric base and a non-bonded portion that is not bonded to the dielectric base;
the radio IC element is arranged to be adjacent to the first surface of the dielectric base;
the portion of the radiation element on which the radio IC element is mounted and a portion of the radiation element facing the end surface are not bonded to the dielectric base; and
a portion of the radiation element facing the second surface is bonded to the dielectric base.

Abstract
A radio IC device includes a flexible dielectric base, a radiation element that is a metal film or a metal foil wrapped around the dielectric base, and a radio IC element mounted on the radiation element. The radiation element includes, in a portion other than a portion where the radio IC element is disposed, a bonded portion that is bonded to the dielectric element and a non-bonded portion that is not bonded to the dielectric element. The radio IC element is arranged to be directly opposed to the dielectric element with the portion of the radiation element where the radio IC element is disposed not bonded to the dielectric base.
