PROBLEM TO BE SOLVED: To provide a cooling storage capable of keeping successful ventilation efficiency for a long time. SOLUTION: This cooling storage 100 comprises a main body 1, an axial flow fan 52 sucking a gas for cooling a radiating portion 41 of the main body 1, a suction opening 63 formed on a bottom surface 8 of the main body 1 for allowing a gas sucked by the axial flow fan 52 to flow in, an air discharge opening 64 formed on a top surface 10 of the main body 1 for allowing the gas sucked by the axial flow fan 52 to flow out, an air duct 60 communicating the suction opening 63 and the air discharge opening 64 for circulating the gas, and a filter 7 disposed in the air duct 60, the air duct 60 has an air duct upstream portion 61, an air duct relay portion 62 and a heat exchanger chamber 50, a flow channel cross-sectional area of the air duct upstream portion 61 is larger than that of the air duct relay portion 62, the filter 7 is disposed on the air duct upstream portion 61, and an area of the filter 7 is larger than the flow channel cross-sectional area of the air duct relay portion 62.
