Abstract
A filter element is made of a first filtering member, and a second filtering member that is arranged on a downstream side of the first filtering member and is impregnated with an oil. The first filtering member consists of a downstream wet layer that is impregnated with the oil, which is transferred by contact to the second filtering member, and an upstream dry layer that is not impregnated with the oil. A density of the first filtering member may be set smaller than that of the second filtering member.
