A pleated filter includes a filter base having folds that repeatedly form peak portions and valley portions and having a shape of a cylinder whose axial direction is a ridge line direction of the folds, and a reinforcing sheet disposed in a valley portion viewed from the inside of the shape of the cylinder. The reinforcing sheet includes a first reinforcing sheet located on a back side of a fold forming a projection toward the outer circumferential side of the shape of the cylinder and a second reinforcing sheet located in a spacing between adjacent folds forming projections toward the inner circumferential side of the shape of the cylinder. The first reinforcing sheet and the second reinforcing sheet are disposed apart from each other in a depth direction of pleats of the pleated filter.
