Abstract
An intake manifold includes a manifold body and a joint. The joint is made of metal and includes an upstream-side portion and a downstream-side portion that are joined to each other. The upstream-side portion is joined to a manifold body on the upstream-side of the manifold body. The downstream-side portion is joined to the manifold on the downstream-side of the manifold.
