Abstract: Provided is a highly convenient and downsizable terminal device, which realizes, even when more than two contactless information communication units, each utilizing a different frequency band, are mounted on a single IC tag, good communication in each of the different frequency bands. The terminal device has two contactless information communication parts (circuit units, such as an inlay, inlet, chip or the like), which utilizes different frequency bands (for example, the HF band and the UHF band, which is higher than the HF band) performs transmission and reception of signals with two antennae being electric-field-coupled to each other.
