A sanitary article is equipped with a moisture-detecting RFID tag that includes a moisture-absorptive material; a moisture-detecting RFID tag adjacent to the moisture-absorptive material; and a relay antenna that is connected to the moisture-detecting RFID tag and that extends the communication range by relaying an output of the moisture-detecting RFID tag. Moreover, the moisture-detecting RFID tag includes an RFIC element, and an antenna element that is connected to the RFIC element. The moisture-detecting RFID tag outputs a variation of a communication distance or a signal intensity, originated from a variation of a moisture amount included in the moisture-absorptive material.
