[PROBLEMS] To provide a tag tape roll in which integrity can be sustained. [MEANS FOR SOLVING PROBLEMS] A plurality of substantially sheetlike antenna substrates (160) each provided with a wireless tag circuit element (To) equipped with an IC circuit section (151) for storing information and a tag side antenna (152) for transmitting/receiving information are arranged continuously in the longitudinal direction of a tape at predetermined intervals to produce a substrate tape (210). The substrate tape is then wound around an axis substantially perpendicularly intersecting the longitudinal direction of the tape, thus obtaining a substrate tape roll (102). The antenna substrates (160), an IC chip holding member (161), and the tag side antenna (152) are arranged on the substrate tape (210) such that the central position (161a) of the IC chip holding member (161) is separated by a predetermined distance (H) from the central position (160a) of a corresponding antenna substrates (160).
