PROBLEM TO BE SOLVED: To provide a stacked heat exchanger capable of preventing the generation of turbulent flow in a circumferential area of a connection port, and reducing a dead water region. SOLUTION: This stacked heat exchanger is constituted by stacking a plurality of plates, and high-temperature fluid passages in which high-temperature fluid flows and low-temperature fluid passages in which low-temperature fluid exchanging the heat with the high-temperature fluid, flows are alternately stacked between the plates. At least one of the fluid passages is provided with the connection port for connecting between the upper and lower plates, and provided with a fluid communication passage communicated with the other fluid passage. An outer wall face of the connection port extends straightly or in a curved line, and forms a tip portion gradually converging. COPYRIGHT: (C)2006,JPO&NCIPI
