    Patent number: 10946325
    Abstract: There is a need to reduce the amount of overlapping parts of a nonwoven fabric of a filter component to thereby lengthen the life of the filter component. This need is met by the filter component formed of a cylindrical nonwoven fabric having a center axis, and having a plurality of polygon-shaped cross-sections which are a same shape that are formed side-by-side at predetermined intervals along the center axis. Each side of each of the polygons is formed by a mountain fold part on a plane perpendicular to the center axis, and each vertex of one polygon is connected by a mountain fold part to each vertex of another polygon, respectively.
