<p>In honeycomb filter 20, capturing layers 24 which are layers that capture and remove solid components in a fluid are formed on a porous partition portion 22 that forms a plurality of cells 23 each having one end open and the other end sealed and functioning as a channel of a fluid. The capturing layers 24 are formed so that the thickness has a tendency to decrease from an outer peripheral region of the honeycomb filter toward a central region of the honeycomb filter, the central region and the outer peripheral region being included in an orthogonal plane orthogonal to the cells 23. In this manner, the outer side, which is less likely to burn and remove the solid components, is made less likely to capture the solid components, and a central side, which is easy to burn and remove the solid components, is easy to capture more solid components.</p> |
