A pleated filter cartridge includes a pleated filter that includes a filter base having folds that repeatedly form mountains and valleys and having a tubular shape whose axial direction is a ridge line direction of the folds, and fixing members disposed on an upper bottom portion and a lower bottom portion of the pleated filter. The pleated filter includes a reinforcing structure for folds in the mountains which are projecting portions projecting toward the outside of the tubular shape. The reinforcing structure includes both a resin-reinforcing structure including, as a reinforcing body, a resin that covers a surface of the base in the folds or a resin that is allowed to permeate in the base in the folds, and a member-reinforcing structure in which reinforcing members provided separately from the filter base are disposed so as to extend along the folds.
