Abrégé
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 being formed by a mountain fold part on a plane perpendicular to the center axis, in which in the plurality of polygon-shaped cross-sections, among polygons that are adjacent to each other, each vertex of one polygon is connected by a mountain fold part to each vertex of another polygon, respectively, in which a valley fold part is formed between adjacent mountain fold parts among the mountain fold parts connecting each vertex of the one polygon with each vertex of the another polygon, and the mountain fold part and the valley fold part are connected at one vertex in the one polygon, and the valley fold part is connected to a vertex neighboring a vertex in the another polygon to which the mountain fold part is connected, and in which the valley fold part is formed at an inclination with respect to the center axis.
