PROBLEM TO BE SOLVED: To provide a plate-type heat exchanger capable of suppressing equipment expenses for manufacturing the heat exchanger and being easily processed. SOLUTION: In this plate-type heat exchanger 1 wherein a plurality of frame bodies 3 having opening portions inside and flat plates are stacked in stages to form spaces of several stages in the stacking direction, flow channels 10a for a fluid A and flow channels 10b for a fluid B are alternately formed in the stacking direction, the fluid A is allowed to flow in and out to the flow channels 10a for the fluid A through a fluid A inlet tube 11 and a fluid A outlet tube 12, the fluid B is allowed to flow in and out to the flow channels 10B for the fluid B through a fluid B inlet tube and a fluid B outlet tube, and the fluid A and the fluid B exchange heat with each other through the flat plates 2a, 2b, one or a plurality of torsion plates 5 are disposed in the flow channels 10a for the fluid A and the flow channels 10b for the fluid B.
