A label producing device for producing an RFID label using a tag label tape with print includes a tape feed roller for feeding the tag label tape with print, a print head for performing printing on a print area provided in a cover film, a half-cut unit for cutting, on both end sides in the tape length direction of the tag label tape with print with respect to the print area, layers other than a separation sheet in the width direction to thereby form half-cut lines, and a cutting mechanism for cutting the tag label tape with print in the width direction on sides further toward the both ends in the tape length direction with respect to these two half-cut lines.
