PROBLEM TO BE SOLVED: To keep inside temperatures of storage compartments roughly the same as one another in an indirect cooling type cooling storage comprising the plurality of storage compartments. SOLUTION: One long evaporation pipe 30 constituting an evaporator 25 is continuously laid in a state of being closely kept into contact with back faces of cooling wall surfaces 14 over from the upper storage compartment 15A to the lower storage compartment 15B or from the lower storage compartment 15B to the upper storage compartment 15A in order of a right side face, a back face, a left side face, a lower face and a top face. As the piping length of the evaporation pipe 30 is long, pressure loss generates between an inlet side and an outlet side, the evaporation temperature is changed in the evaporation pipe 30, so that the evaporation temperature at the outlet side is lower than that at the inlet side, for example, by about 3K. As a piping part of high evaporation temperature and a piping part of low evaporation temperature are respectively separately distributed on the storage compartments 15A, 15B, as a result, an average wall surface temperature in the storage compartments 15A, 15B is roughly equalized, and the inside temperatures of the storage compartments 15A, 15B are kept roughly same as one another.
