A heat exchanger 10 includes a first block and a second block. The first block includes a first tank T1 having a refrigerant inlet through which the refrigerant flows in, a plurality of first tubes 21 into which the refrigerant having flowed into the first tank T1 is distributed and flows therein, and a second tank T2 in which the refrigerant flowing in the first tubes 21 merges. The second block includes a third tank T3 into which the refrigerant having merged in the second tank T2 flows therein, a plurality of second tubes 22 into which the refrigerant having flowed into the third tank T3 is distributed and flows, and a fourth tank T4 in which the refrigerant flowing in the second tube merges, and having a refrigerant outlet through which the merged refrigerant flows out. A refrigerant passage 43h through which the refrigerant flows from the second tank T2 into the third tank T3 is locally placed on the opposite side of the refrigerant inlet.
