PROBLEM TO BE SOLVED: To provide a control device of a showcase, capable of controlling the inside temperature of the showcase to substantially the same temperature as a set temperature regardless of setting environment or the like, and an integrated control device of showcases. SOLUTION: The control device 15 of showcase adapted to control the inside temperature by thermo-ON and thermo-OFF of a solenoid valve 14 for supplying refrigerant to an evaporator comprises a reference temperature calculation part 21 calculating an inside reference temperature in a predetermined measuring period from a measured inside temperature, and a temperature change part 23 comparing the inside reference temperature with a set temperature of the showcase and changing, base on the result, the time of thermo-OFF of the solenoid valve 14 so that the inside reference temperature is within a predetermined range including the set temperature.
