PURPOSE: An intake manifold structure is provided to increase distribution property of EGR gas without a separate EGR adapter using an EGR connection part and a heat injury prevention member. CONSTITUTION: An intake manifold structure comprises an EGR(Exhaust Gas Recirculation) connection part(310). The EGR connection part is included on a flange(300) of the intake manifold. Each suction pipe(200) is interlinked. The EGR connection part comprises a linking groove(311) and a connection pathway(312). The linking groove is formed in the surface of the flange. The connection pathway interlinks the suction pipe and the linking groove. A bottom plate(321) is supported in the floor side of the EGR connection part. A side board(322) is supported in the inner wall of the EGR connection part.
