In an intake manifold of an internal combustion chamber comprising a surge tank assembly and intake pipe assembly, a seal member is interposed between the end surface of the intake pipe assembly and the mating surface of the surge tank assembly so as to seal off the intake passage and mounting holes individually. Thus, the seal member, combined with the use of the blind threaded holes for the threaded bolts joining the two parts, ensures the sealing of both the intake passages and mounting holes at the interface between the end surface of the intake pipe and the mating surface of the surge tank assembly in a both reliable and simple manner. Preferably, the seal member comprises an O-ring made of elastomeric material, and at least one of the mating surface and end surface is provided with a groove for receiving the seal member.
