PROBLEM TO BE SOLVED: To provide an exhaust manifold capable of preventing generation of air stream noise and strike noise, and increase of duct resistance by making flow of exhaust gas flowing into an aggregation part constant even if an exhaust gas upstream side end part of the aggregation part is formed in a bent shape. SOLUTION: In the exhaust manifold A1 having a part around the exhaust gas upstream side end part 6a of the aggregation part 6 formed in the bent shape, exhaust gas downstream side end parts 3b-5b of each branch pipe 3-5 are communicated with and connected to the exhaust gas upstream side end part 6a of the aggregation part 6 under a condition where the same are set in an inclined shape projecting to an exhaust gas downstream side as getting to a bent outside 6b.
