The present invention addresses the problem of providing an intake manifold which enables interference of the intake manifold with a fuel injection valve during a vehicle collision to be controlled. This intake manifold (2) has a joint surface (32b) of a flange part (31) and a joining part (33) which are joined such that an extension line (L) of the joint surface (32b) and a joint surface (33a) of the joining part (33) is oriented towards a position clear of a fuel injection valve (10). Furthermore, the joining part (33) of the intake manifold (2) is formed such that a length (A) in the extension direction of the joint surface (33a) is longer than the longest distance (B) separating the fuel injection valve (10) and the flange part (31).
