An evaporatorincludes a refrigerant inlet header sectionand a refrigerant outlet header sectionwhich are arranged in the front-rear direction, a refrigerant circulation passage for establishing fluid communication between the header sectionsand. First ends of the header sectionsandare closed with a first capand the second ends thereof are closed with a second cap. A refrigerant inletand a refrigerant outlet are formed in the first cap. A pipe joint member, having a refrigerant inflow portcommunicating with the refrigerant inletand a refrigerant outflow portcommunicating with the refrigerant outlet, is joined to the first cap. Mating concave portionsandare formed on the first cap. Mating convex portionsandwhich project toward the first capand which are to be fitted into the mating concave portionsand, respectively, are formed on the pipe joint member. The second caphas no mating concave portions into which the mating convex portionsare fitted. The evaporator () to which the heat exchanger of the present invention is applied can prevent erroneous attachment of the pipe joint member during manufacture thereof.
