PROBLEM TO BE SOLVED: To provide a stacked heat exchanger having high performance and compact size. SOLUTION: Rectangular and corrugated crest rows 4 and trough rows 5 are alternately arranged side by side in a line on one sheet polygonal heat transfer plate having heat transfer property. The heat transfer plates are stacked in multi-layer so that two independent systems of fluid passages 10, 11 are alternately arranged in the same direction in the direction perpendicular to the stacking direction by the mutual crest rows 4 and the mutual trough rows 5, thereby constituting a polyhedron in which the inflow and outflow parts 8 of the two systems of the fluid passages 10, 11 respectively face to individual faces. In this arrangement, a primary fluid A and a secondary fluid B are let flow in the opposite directions through two systems of fluid passages 10, 11.
