PROBLEM TO BE SOLVED: To provide an oil mist separator which improves the sealability around a nozzle hole to improve the oil separation efficiency and the productivity.SOLUTION: An oil mist separator 1 is disposed in a cylinder head part of an engine and separates an oil component from a blow-by gas. The oil mist separator 1 includes: a resin cylinder head cover 3 where a bottom surface opens; and a resin baffle plate 5 which is disposed so as to close the bottom surface of the cylinder head cover. An expansion part 7 which expands upward is formed at the baffle plate. Nozzle holes 9 for circulating the blow-by gas are formed at wall parts 7A, 7B forming the expansion part. A collision plate 11, with which the blow-by gas having a flow velocity increased when the blow-by gas passes through the nozzle holes collides, is provided at the downstream side of the nozzle holes. |
