Abstract: The present invention provides an oil separator that can improve oil separation performance with a simple structure. An oil separator 10 includes a casing 15 that has an inlet 11 and an outlet 12 and the oil separator 10 is configured to separate oil contained in blow-by gas 2 in the casing 15. The casing 15 includes therein multiple staggered partition walls 25, 35 to form a gas passage 40 through which the blow-by gas 2 flows in a meandering manner in a horizontal direction from the inlet 11 to the outlet 12, and a filter element 50 that partially closes the gas passage 40 and crosses the partition walls 25.
