Abstract
An intake manifold has a collective part defining an intake gas distribution chamber, and a branch intake part having a plurality of branch intake passages. The collective part includes a first section and a second section joined together to form the intake gas distribution chamber. First and a second corner parts are formed integrally with the first section and the second section, respectively. The second section is provided with a guide wall extending in both the first and second sections to cover the respective inside surfaces of the first and second corner parts. The guide wall has a guide surface for guiding the intake gas.
