PROBLEM TO BE SOLVED: To provide an evaporator capable of improving heat exchanging efficiency by uniformly distributing a two-phase refrigerant flowing in a tank to tubes. SOLUTION: In this evaporator composed of the tubes 1 forming flow channels 4 for circulating the two-phase refrigerant 9, fins mounted among the tubes arranged at specific intervals, and the tank 3 to which both end parts of the tubes 1 are inserted, first introduction holes 7 for introducing a vapor-phase refrigerant 9b into the tubes 1 are mounted at the neighborhood parts of the bases to the tank 3, of the tubes 1 inserted into the tank 3, and second introduction holes 8 for introducing a liquid-phase refrigerant 9b into the tubes 1 are formed at lower ends of the tubes. By independently forming the holes for the liquid-phase refrigerant 9a and the holes for the vapor-phase refrigerant 9b, two-phase refrigerant 9 can be uniformly distributed into the tubes 1.
