    • A thermal activation method for a heat-sensitive adhesive sheet is provided, in which the adhesive sheet has an adhesive layer, which can be rendered adhesive by heat generated by driving a linear array of heating elements (10) of a thermal head (11). The method includes: the step of selectively driving the plurality of heating elements by choosing in advance which at least one of the plurality of heating elements is to temporarily stop being driven and by setting in advance when to stop driving this heating element, in a manner that gives a first region, that is not heated by any opposing heating element, a location and a size that allow the first region to be thermally activated with heat transmitted from a second region, the second region surrounding the first region and being heated by opposing heating elements, the first and second regions constituting a predetermined region, the entirety of which is to develop adhesion; and the step of thermally activating the adhesive layer throughout the predetermined region by thermally activating the heat-sensitive adhesive layer in the first region with heat transmitted from the second region, the heat being transmitted to the first region laterally through the heat-sensitive adhesive layer (1a), the dissipation of the heat in a depth direction of the heat-sensitive adhesive sheet being limited due to the existence of the heat insulating layer (1c). By this means, a sticking power is developed which is substantially equivalent to that obtained when all the heating elements facing the predetermined region are driven. This substantially equivalent sticking power is achieved with a driving energy which is less than a driving energy in a case where all the heating elements which face the predetermined region are driven.
