Patent ID: 8692674

Claim:
A tag tape roll comprising a tag tape wound around an axis which is substantially perpendicular to the lengthwise direction of the tag tape, wherein: a plurality of substantially sheet-like antenna bases are consecutively arranged on said tag tape at predetermined intervals in the lengthwise direction of the tag tape, an RFID circuit element provided with an IC circuit part that stores information and an antenna that transmits and receives information is disposed on said antenna bases, and said antenna base, said IC circuit part, and said antenna on said tag tape are arranged so that the center position of said IC circuit part is separated by a predetermined distance Ha in the lengthwise direction of said tag tape from the center position of the corresponding antenna base, said predetermined distance Ha is −0.2≦Ha/L≦0.9 (where Ha/L≠0), when the length of said antenna base in the tape length direction is 2L, and a positive value is gained in the opposite direction to the fed-out direction of said tag tape.
