In this case, the set temperature of the thermostat 15 (the temperature at which the power to the heater is cut off) is set to a temperature that is much higher than the optimum temperature for bonding the tape, and functions as a kind of safety device. It has become. That is, even if the thermistor 14 or the like does not operate normally, the circuit can be cut off by the thermostat 15 so that the temperature of the heater 13 can be maintained at a predetermined value or less. Further, the thermistor 14 includes the heat storage unit 1.
