Title: IC tag and inlet for IC tag

Abstract: An IC tag mounting at least two IC chips operating in different frequency bands. The IC tag having a first inlet including a first antenna having a relatively long operation wavelength and a first IC chip mounted on the first antenna, and a second inlet including a second antenna having an operation wavelength shorter than the first antenna and disposed crossing at a predetermined angle over a line of the first antenna without positioning both opposite ends of the second antenna upon the first antenna and a second IC chip mounted on the second antenna. The second antenna has a matching circuit for impedance matching between the second antenna and the second IC chip. The matching circuit is a slit formed in the second antenna and positioned upon terminals of the second IC chip. Thus, the second antenna is made compact using the first antenna as an auxiliary antenna.
