Provided is a honeycomb structure with which reduction in filter performance due to the occurrence of circular cracks can be limited and the expansion of circular cracks can be limited. The invention is a columnar honeycomb structure (10) that extends along a central axis (CL). The structure has a first end face (10a) and a second end face (10b) that are opposite to each other in the direction of the central axis (CL) and partition walls (10c) that form multiple first flow paths (Ra) and multiple second flow paths (Rb) that extend along the central axis (CL). The first flow paths (Ra) are open on the first end face (10a) side and closed on the second end face (10b) side. The second flow paths (Rb) are closed on the first end face (10a) side and open on the second end face (10b) side. The ratio of openings in the first end face (10a) is greater than the ratio of openings in the second end face (10b). When viewed from the direction of the central axis (CL), the structure has a ring-shaped row (W) formed by arranging second flow paths (Rb), which are adjacent across partition walls (10c), in a ring.
