PROBLEM TO BE SOLVED: To provide a hot-keeping/cold-keeping coaster for beverage of which the power consumption is greatly reduced. SOLUTION: This hot-keeping/cold-keeping coaster for beverage is equipped with a coaster main body 10, and an electronic heat pump module 1 which cools one surface side of the coaster main body 10, and in the meantime, heats the other surface side of the coaster main body 10. The electronic heat pump module 1 is equipped with a vacuum diode type electronic heat pump device, and therefore, the power consumption can greatly be reduced more than by a cooling mechanism of a Peltier element.
