PROBLEM TO BE SOLVED: To provide a showcase preferable from a viewpoint of environmental protection, and cooling commodities by efficiently transporting cold heat generated from a Stirling refrigerating machine to a commodity housing box. SOLUTION: This showcase 1 is provided with: the commodity housing box 13 arranged in a case body 10; and the Stirling refrigerating machine 20 used as a cooling source for commodities housed in the commodity housing box 13. The showcase is also provided with: a condensation heat exchanger 31 condensing a refrigerant flowing through a passage by cold heat generated from a low-temperature part 21 of the Stirling refrigerating machine 20; an evaporation heat exchanger 32 cooling the commodities in the commodity housing box 13 by evaporating the refrigerant flowing through an evaporation passage 32a arranged in a form winding around the commodity housing box 13; and a cold heat transport means 30 having a liquid line 33 delivering the refrigerant from the condensation heat exchanger 32 to the evaporation heat exchanger 32, and a liquid line 34 returning the refrigerant from the evaporation heat exchanger 32 to the condensation heat exchanger 31.
