Patent ID: 8905296

Claim:
A wireless IC device comprising: a base material sheet that has a substantially rectangular shape having a long-side direction and a short-side direction; an antenna element that is provided on a surface of the base material sheet and that has two radiation parts extending in the long side direction with a predetermined gap therebetween and two connection parts located in the gap through which the two radiation parts oppose each other; a wireless IC element that is connected to the two connection parts via a conductive bonding material; and a resist layer that regulates the movement of the conductive bonding material; wherein the resist layer covers the two radiation parts and does not cover the two connection parts and at least areas adjacent to the connection parts in the short-side direction; and wherein the resist layer is completely divided in the long-side direction so as to separately cover the two radiation parts and so as not to cover the two connection parts and entire areas extending from each of the two connection parts to side surfaces of the base material sheet in the short-side direction.
