たことを特徴とする積層形オイルフイルタ。 In a laminated oil filter in which a filter element in which filter papers are laminated in multiple stages is housed in a cylindrical case, the filter paper has a polygonal shape cut out from the peripheral edge of a disk having a center opening that contacts the inner peripheral edge of the cylindrical case; and a plurality of grooves are formed radially from the inscribed portion of the filter paper toward the central opening, and a crescent-shaped groove is formed between the inner peripheral edge of the case and each side of the polygonal shape of the laminated filter paper. A laminated oil filter characterized in that oil supplied to the gap permeates from the outer periphery of the filter paper to the inner periphery side and flows to the inner periphery side using the striation grooves as oil passages.
