PROBLEM TO BE SOLVED: To provide an adhesion realization unit which realizes stable and sufficient adhesion by melting a functional layer with sufficient openings while suppressing breaking of the functional layer covering an adhesive layer.SOLUTION: An adhesion realization unit realizes an adhesion by heating an adhesive label 10 which has an adhesive layer coated with a non-adhesive functional layer and includes a thermal head which has a plurality of heater elements and heats the adhesive label carried along the carrying direction F from the side of the adhesive layer to form openings in the functional layer so as to expose the adhesive layer, and a control part for controlling heat generation of the heater elements. The control part controls application of heat to the heater elements in such a way as to cause at least two of adjacent heater elements to generate heat simultaneously so as to form a group of openings connected in the width direction, in forming an opening line in which openings are arranged in the width direction W of the adhesive label.
