PROBLEM TO BE SOLVED: To provide a structure of a heat exchanger suitable for reducing the inner diameter size of a tank with respect to a tube width, and further to provide the dimensional numerical value relationship of the heat exchanger capable of keeping refrigerant distributing performance and achieving both reductions in size and weight. SOLUTION: In this heat exchanger, the inner diameter size of the tank with respect to the tube width is reduced, and a relation 15≤L/Dt≤42 is satisfied when the equivalent diameter of a cross-section of a passage of the tank is Dt, and the length of the longest passage from an inlet part to the opening end of each tube is L.
