An EGR plate member configured of an EGR plate inner and outer is interposed between a cylinder head and an intake manifold, including an exhaust gas recirculation passage formed therein. The EGR plate member has a lower protruding portion to protrude outward beyond respective connecting faces thereof with the cylinder head and the intake manifold. A common passage portion of the exhaust gas recirculation passage is substantially formed at the protruding portion. Part of the common passage portion has its laterally-long cross section which is offset toward the cylinder head. The offset portion of the EGR plate member has its greater thickness than other part thereof, extending below an intake port flange portion. Accordingly, the exhaust gas can be cooled by an outside air, thereby reducing an improper heat influence on the intake manifold.
