PROBLEM TO BE SOLVED: To provide a filter structure and a method of manufacturing the same which can increase a space volume in a sealed cell while sufficiently securing adhesion strength and durability of a plugged part for sealing the sealed cell, and can improve performance. ! SOLUTION: A filter structure 1 includes a porous partition wall part 2, and a plurality of cells 3 which are partitioned by the partition wall part 2 and are formed by penetrating in an axial direction X. The one cell 3 out of the plurality of cells 3 is a sealed cell 31 of which opening end parts 311 on both sides in the axial direction X are sealed by plugged parts 4. The plugged part 4 includes a dent part 41 which is formed by denting in the axial direction X from an inner side of the sealed cell 31 to an opening end 310 side in a region on the opening end 310 side of the sealed cell 31 than an innermost end position A of a contact part with an inner wall surface 200 of the partition wall part 2. !
