To obtain a tack label using two sheets of a substrate so as to afford itself with moderate mechanical strength and also apply itself onto an object article and release part of the substrate to be suitable for putting it to another use.

This tack label is so designed that, the reverse face of a 1st substrate 5 is provided with a re-releasable tack agent layer 6 enabling repeated adhesion and release, while a 2nd substrate 2 is bonded to the surface of the 1st substrate via such as adhesion structure that, after releasing a part of the 2nd substrate, the part runs no longer re-adhesive (pref. such a structure as to laminate the 2nd substrate 2 with a releasable layer 3 followed by a synthetic resin intermediate layer 4) and the rest of the 2nd substrate is bonded to the 1st substrate via no such adhesion structure, wherein it is preferable that the boundary between the part being in adhesion via the above structure and the part with no such adhesion structure is furnished with perforated line for separation, half-cut or line press reaching the 2nd substrate 2 to at least non-readhesive adhesion structure, and furthermore, the 1st substrate 5 has such a portion as to be larger than the 2nd substrate 2 and therefore not partially superposable thereupon.
