PROBLEM TO BE SOLVED: To provide an evaporator capable of lengthening an on/off cycle of a compressor.SOLUTION: An evaporator has a plurality of flat-shaped cooling medium circulation tubes 6 which are arranged in a state where a longitudinal direction is directed in a vertical direction, and a width direction is directed in a ventilation direction. In the cooling medium circulation tube 6, a corrugated-shaped inner fin 17 is arranged which has: a corrugated top part 17a extending in the vertical direction; a corrugated bottom part 17b extending in the vertical direction; and a connection part 17c connecting the corrugated top part 17a and the corrugated bottom part 17b. At the inner fin 17, a resistance imparting part 21 is provided for imparting resistance to a downward flow of the cooling medium. The resistance imparting part 21 is formed in at least one of the corrugated top part 17a and the corrugated bottom part 17b of the inner fin 17 with an interval in the vertical direction, and it comprises a plurality of deformation parts dented inward of the cooling medium circulation tube 6. |
