To provide a wristband which is surely operated to be wrapped around a part to be wrapped around, such as a wrist or an ankle, and is wrapped to ensure a proper and accurate ring shape.

Differently from a conventional method of sticking a rear surface of one of both end parts of a band base material 2 and a front surface of the other to each other, rear surfaces of the both end parts are first stuck to each other. A rear surface of a first wrapping region 6 having an exposed adhesive layer 3 (first sticking region 22) and a rear surface of a wrapping region 7 are put one over the other and are stuck to each other with a part (second sticking region 23) of the adhesive layer 3 left exposable so that first sticking position guides 18 and 19A and a second sticking position guide 19 are aligned with each other, whereby the band base material can be formed like a ring so as to be wrapped around a part to be wrapped around. The first wrapping region 6 having a part (second sticking region 23) of the adhesive layer 3 left exposable can be stuck to a front surface of the second wrapping region 7.
