Abstract: Provided is an antenna device that performs the reading of information via near field wireless communication by using a plurality of antenna patterns, and that has no insensitive area on the touch surface. An antenna device that reads information via near field wireless communication includes an antenna layer 20 that includes a plurality of antenna patterns 21a to 21l arrayed in parallel with one another, wherein at least a part of the antenna patterns 21a to 21l are arranged so as to overlap with one another when the antenna layer 20 is viewed in a plan view.
