PROBLEM TO BE SOLVED: To provide a heating/cooling storage including a plurality of storage chambers for storing objects and adapted to store the objects with heating or cooling by use of Peltier elements, which can easily respond to various users' purposes by enabling efficient hot storage/cold storage of the object stored in each storage chamber at a desired temperature. SOLUTION: Each storage chamber of a food service cart 1 includes a hot storage chamber 11 and a cold storage chamber 12. A machine chamber 20 includes, for each storage chamber, a hot storage Peltier element 21 for heating the hot storage chamber 11, a cold storage Peltier element 22 for cooling the cold storage chamber 12, a heat sink in contact with opposed faces of both the Peltier elements, and a blowing fan 23 for forcedly radiating heat of the heat sink 24. The temperature control of the hot storage chamber 11 and the cold storage chamber 12 is performed by control of rotating speed of the blowing fan 23 based on temperature data from a hot storage chamber thermistor 61 and the like, and on/off control to both the Peltier elements is performed only when the temperature control by the blowing fan 23 cannot be performed.
