Abstract: The tube-shaped pleated filter member may comprise: a filter body having a tube shape such that a filter medium is pleated and is wound; and a support unit. The filter body may comprise outer pleated portions corresponding to the outside of the tube shape, and inner pleated portions corresponding to the inside of the tube shape. An inner virtual line connecting corners of the inner pleated portions may have the shape in which a unit wave shape recessed in the outward direction is repeated. Assuming, that the thickness at a part having the maximum distance between the inner virtual line and the outer virtual line is a first thickness (T1), the first thickness (T1) may have a range defined by [equation 1] with regard to the diameter (D) of the outer virtual line. D/15≤T1≤D/6. [Equation 1]
