PROBLEM TO BE SOLVED: To improve design flexibility of an IC tag.SOLUTION: An IC tag includes an IC chip and a dipole antenna. The dipole antenna includes: a first element section having first and second areas extending in a first direction; and a second element section having first and second areas extending in the first direction and arranged so that ends of the first areas face each other at a predetermined distance in the first direction; and an impedance matching section which forms a gap area between the impedance matching section and the first areas in a second direction orthogonal to the first direction by connecting the second areas in the element sections, to establish impedance matching between the IC chip and the dipole antenna; and a pair of lead wire sections extending from the ends of the first areas to a side opposite the impedance matching section in the second direction. The IC chip is connected to the pair of lead wire sections so as not to overlap the first and second elements sections. |
