PROBLEM TO BE SOLVED: To suppress temperature rise of an interior cooled space and articles stored in the space by suppressing clogging due to frost by a simple configuration and elongating an interval of defrosting operation. SOLUTION: This evaporator 5 includes: a plurality of heat exchange fins 51A, 51B arranged at least at a predetermined interval; and refrigerant piping 60 penetrated through the heat exchange fins 51A, 51B and extended meanderingly. The evaporator 5 is arranged together with an air blowing fan in an air course for circulating cold air in a storage chamber 3. Part of the heat exchange fins 51 on the face on an air inlet side in the air course within the evaporator 5 and/or on the upper face of a refrigerant inlet of the evaporator 5 is cut, so that the interval between the heat exchange fins 51 on the face is expanded compared to the predetermined interval.
