Abstract
A honeycomb filter 20 includes a trapping layer 24 having a high porosity region 24b and therefore has lower permeation resistance in the vicinity of a surface of a partition portion 22 than a honeycomb filter having no high porosity region 24b. This can reduce pressure loss, for example, when a fluid passes through the honeycomb filter 20 at a high flow rate. The high porosity region 24b has a 10% or more higher porosity than a non-high-porosity region 24a. This ensures a reduction in permeation resistance in the vicinity of the surface of the partition portion and ensures the effect of reducing pressure loss.
