The present invention relates to an evaporator (1000) and, more specifically, to an evaporator (1000), in which refrigerant is uniformly distributed to each area through 8-pass flow from a first area (A1) to an eighth area (A8) so as to reduce temperature variation and maximize the heat exchange efficiency with respect to outdoor air, and air is discharged to the left and right sides in a vehicle room with uniform temperature distribution so as to maintain the comfort of passengers.
