Abstract
A heat activation method for activating a thermosensitive adhesive label having a support and a thermosensitive adhesive layer which is formed on the support and is not adhesive at room temperature, so as to make the thermosensitive adhesive layer adhesive with the application of heat thereto, includes the step of bringing the thermosensitive adhesive layer into contact with a surface portion of a heating medium, at least the surface portion of the heating medium being made of a silicone resin and having a peel strength of 2 g/mm or less with respect to the thermosensitive adhesive layer. There is also disclosed a heat-activating apparatus for heat-activating the above-mentioned thermosensitive adhesive label.
