PROBLEM TO BE SOLVED: To provide an intake manifold device that can make a material cost inexpensive.SOLUTION: An intake manifold device 10A includes an intake manifold 12 in which a heat exchanger 14 is built. The intake manifold 12 includes: a first part 18 positioned upstream of the heat exchanger 14; and a second part 20 positioned downstream of the heat exchanger 14 and configured of a second resin material that has a heat resistance lower than that of a first resin material. The first part 18 and the second part 20 are connected to each other by welding.SELECTED DRAWING: Figure 1 |
