A control signal is generated so as to have a large temperature gradient. Thereby, when the amount of heat absorbed (released) from the cooling plate 4 by the Peltier element 6 increases, the cooling plate 4 rapidly approaches the temperature specified by the user.

  In contrast, when the cooling time is set by the user to be long, the control unit 14 determines the temperature specified by the user from the temperature of the cooling plate 4 based on the temperature information generated by the temperature detection sensor 9. The control signal is generated so as to have a small temperature gradient until. As a result, the amount of heat absorbed (released) from the cooling plate 4 by the Peltier element 6 decreases, and the cooling plate 4 slowly approaches the temperature specified by the user.

  The control unit 14 may display the temperature information notified from the temperature detection sensor 9 through the display unit 13 as needed.
