To reliably peel each label from the beltlike base paper of a label strip and to prevent the tear of the base paper from a break in the base paper in the peeling by forming slits in the base paper at the corner parts of each label when a plurality of labels are temporarily stuck to the beltlike base paper at prescribed intervals to obtain the label strip.

When label 3 are temporarily stuck to beltlike base paper 8 at prescribed intervals to obtain a label strip 1a, slits 9, 9 are formed in the base paper 8 at corner parts 3a, 3a formed by the front edge 3b of each of the labels 3 in the peeling direction of the labels (F1 direction) and the lateral edges 3c, 3c of each of the labels 3. The slits 9, 9 are formed from the front edge 3b to the lateral edges 3c, 3c in such a way that they are made oblique to the peeling direction of the labels so as to prevent the tear of the base paper 8 from the slits in the peeling of the labels 3.
