Abstract: A wireless communication device includes a conveyance portion, a sensor, and a communication portion, and conveys a long backing sheet, a plurality of labels, each provided with a wireless tag, being adhered with intervals in a lengthwise direction of the backing sheet. The wireless communication device detects, by the sensor, an end portion on an upstream side of the label including a wireless tag adhered on the backing sheet, while conveying the backing sheet in a conveyance direction by the conveyance portion, and performs a wireless communication with a target label when the backing sheet is conveyed by a predetermined amount in the conveyance direction. The predetermined amount is decided based on a communication state, between the communication portion and the wireless tag, detected at each of positions when the backing sheet is sequentially conveyed to a plurality of positions in the conveyance direction.
