Abstract
A radio-frequency-identification tag antenna includes a film base, a plurality of antenna patterns for transmission and reception, which is formed in parallel on the film base, and a cut line that is formed on the film base between adjacent antenna patterns along the antenna patterns from an inside to an outer edge of the film base. A part of the film base on which the antenna patterns are formed is folded or bent in a predetermined direction using the cut line.
