An EGR cooler including a cylindrical shell having a cooling water inlet for introducing cooling water into the shell at one axial end, a cooling water outlet for discharging the cooling water from the shell at the other axial end, and a bypass outlet for pulling out part of the cooling water at a position diametrically opposed to the cooling water inlet, plates positioned at axial ends of the shell so as to close the axial ends of the shell, hoods positioned at sides of the plates away from the shell so as to enclose end faces of the plates, and tubes extending axially within the shell and having ends penetrating through the plates. The tubes passes exhaust gas from one of the hoods to the other hood for thermal exchange of the exhaust gas with the cooling water.
