PROBLEM TO BE SOLVED: To provide a heat exchanger (an evaporator) having a structure capable of making proportion of gas refrigerant and liquid refrigerant distributed from a tank at a lower part to each tube even. SOLUTION: A refrigerant distribution adjusting plates 34, 35 with weir parts 34a, 35a on a lower side for blocking the refrigerant and openings 34b, 34c, 35b, 35c on an upper side for making the refrigerant pass through are provided in a refrigerant flow passage 31 in a lower part tank 24. Preferably, for the openings of the refrigerant distribution adjusting plate, a plurality of small openings are distributed in a horizontal direction or in the horizontal and vertical direction. An opening rate of the openings of an refrigerant distribution adjusting plate positioned on a downstream side of refrigerant flow direction preferably is smaller than an opening rate of the openings of an refrigerant distribution adjusting plate positioned on an upstream side of refrigerant flow direction.
