Abstract
The honeycomb structure includes a honeycomb structure body having porous partition walls, and a plugging portion disposed in one of open ends of each cell, a thickness of the partition walls is 0.30 mm or more and 0.51 mm or less, a cell density is 30 cells/cmor more and 93 cells/cmor less, a filtration area (cm) of inflow cells included per cmof the honeycomb structure body is defined as an inflow side filtration area G (cm/cm), a value obtained by dividing a pore volume Vp (cm) formed in the partition walls by a total volume Va (L) including the cells is defined as a pore volume ratio A (cm/L), and in this case, a product of the inflow side filtration area G (cm/cm) and the pore volume ratio A (cm/L) is 1800 cm/L or more and 3200 cm/L or less.
