A thermal activation apparatus 1 includes a thermal head 2 for thermal activation, a platen roller 4 for thermal activation pressed against the thermal head 2 for thermal activation, and an air cooling mechanism. The air cooling mechanism includes partitions 5 for separating the thermal activation apparatus 1 from the outside, an air outlet 6 in a lower part thereof, first and second air inlets 7 a and 7 b in an upper part thereof, and a fan 8 for exhausting air in the air outlet 6. While a heat-sensitive adhesive agent layer of the heat-sensitive adhesive sheet 10 is heated by the platen roller 4 for thermal activation and the thermal head 2 for thermal activation to be thermally activated during transporting the heat-sensitive adhesive sheet 10, the fan 8 for exhausting air is actuated to generate airflow A from the first and second air inlets 7 a and 7 b and around the platen roller 4 for thermal activation, the thermal head 2 for thermal activation, and the heat sink 3 in this order to be discharged to the outside from the air outlet 6.
