PROBLEM TO BE SOLVED: To provide a heat exchanger having excellent heat exchange performance, especially when used as an evaporator. SOLUTION: This heat exchanger 1 is has a heat exchange core 4, a coolant inlet header 5 and a coolant outlet header 6 arranged on the upper end side of a heat exchange tube 12, and a coolant inflow side intermediate header 9 and a coolant outflow side intermediate header 11 arranged on the lower end side of the heat exchange tube 12. A flow dividing control wall 67c having a plurality of coolant passage holes 71 for dividing the inside of the second intermediate header 11 into two spaces 11A, 11B in the height direction is formed in the second intermediate header 11. The first intermediate header 9 is communicated made to communicate at one end with the lower space 11B of the second intermediate header 11. A guide part 80 for guiding the coolant entering the lower space 11B of the second intermediate header 11 to the flow dividing control wall 67c side, namely, to the upper side, is formed at the coolant inflow side end of the second intermediate header 11.
