PROBLEM TO BE SOLVED: To provide a refrigerant evaporator for reducing pressure loss of a refrigerant flow while obtaining excellent temperature distribution. SOLUTION: Since a first partition member 17 is arranged in an upper tank 12 of a first evaporation part 1, a core part 11 of the first evaporation part 1 is divided into two of a first turn part 11a and a second turn part 11b in the tube stacking direction. Since a second partition member 27 is arranged in an upper tank 22 of a second evaporation part 2, a core part 21 of the second evaporation part 2 is divided into two of a third turn part 21a and a fourth turn part 21b in the tube stacking direction. A first refrigerant inflow port 18 connected to refrigerant inflow piping 3 for making a refrigerant flow in to the first and second evaporation parts 1, 2 is provided in the first turn part 11a, and a second refrigerant inflow port 28 connected to the refrigerant inflow piping 3 is provided in the third turn part 21a. An end on the refrigerant flow downstream side of the second turn part 11b is connected to an end on the refrigerant flow downstream side of the fourth turn part 21b by a connection part 4.
