Provided is a thermal activation device capable of preventing a heat-sensitive adhesive sheet from being partially excessively heated, keeping a short distance between a contact between a thermal head and a platen roller, and a discharge port, and preventing a structure of the thermal activation device from being complicated and a size thereof from increasing. While a heat-sensitive adhesive sheet ( 2 ) is transported along a transport path ( 15 ) through rotations of insertion rollers ( 3 ) and a platen roller ( 5 ), a heat-generating portion ( 4 a) of the thermal head ( 4 ) is caused to generate heat, thereby thermally activating a heat-sensitive adhesive layer of the heat-sensitive adhesive sheet ( 2 ). When a trailing edge of the heat-sensitive adhesive sheet ( 2 ) reaches a position where the trailing edge thereof is not in contact with the platen roller ( 5 ), a transporting force is not transmitted to the heat-sensitive adhesive sheet ( 2 ), thereby stopping transportation thereof. At that time, an adhesion prevention member ( 6 ) is allowed to enter the transport path ( 15 ) to lift and hold the trailing edge of the heat-sensitive adhesive sheet ( 2 ) to a position where the trailing edge thereof is not in contact with the thermal head ( 4 ).
