Stage: PROBLEM TO BE SOLVED: To provide a honeycomb structure capable of reducing the risk of cracking in the honeycomb structure when heated and a method for producing the same.SOLUTION: There is provided a honeycomb structure 1 which has a honeycomb structure part 2 having an outer peripheral wall 20 and a partition wall 21 which is arranged inside the outer peripheral wall 20 and dividedly forms a plurality of cells 21a forming a flow channel extending from one end face to the other end face and further has a plurality of slits 3 extending radially inwardly from an outer peripheral surface of the honeycomb structure 1 and extending in the extension direction of the cells 21a and a filler 4 filled in the plurality of slits 3, wherein when the difference between a width Y of the filler 4 and a width X of the slit 3 represented by the following expression (1) is determined for each slit 3, the difference between a maximum value A of the difference and a minimum value B of the difference represented by the following expression (2) is 0.4 mm or less. In the expression (1), X represents the width of the slit 3 on the outer peripheral surface of the honeycomb structure 1 and Y represents the width of filler 4 when looking at the filler 4 from the outside in the radial direction. Expression (1) Y-X. Expression (2) A-B.SELECTED DRAWING: Figure 1 (Grant)
