    摘要： Provided is a honeycomb structure including a honeycomb substrate having partition walls defining cells extending from an inflow end face to an outflow end face, and plugging portions. The cells include at least one cell group consisting of a both-end plugged cell, an inlet cell adjacent to the both-end plugged cell, and an outlet cell adjacent to the both-end plugged cell. The partition walls defining the both-end plugged cell have a first common partition wall defining both of the inlet cell and the both-end plugged cell, and a second common partition wall defining both of the outlet cell and the both-end plugged cell. A first flow-through hole is formed in an end portion of the first common partition wall on the outflow end face side, and a second flow-through hole is formed in an end portion of the second common partition wall on the inflow end face side.
