Honeycomb filter and method for manufacturing honeycomb filter

A method for manufacturing a honeycomb filter for trapping and removing solid components contained in a fluid, comprising:

• a trapping layer forming step of forming a trapping layer in a honeycomb structure that includes a plurality of porous partition portions, the trapping layer being a layer for trapping and removing solid components contained in the fluid, each of the partition portions forming a cell that is open at one end and closed at the other end and serves as a flow path of a fluid;
• an entire catalyst forming step of bringing the entire honeycomb structure into contact with a catalyst component to form a catalyst;
• and
• a partial catalyst forming step of bringing only an upstream region of the honeycomb structure into contact with a catalyst component to form a catalyst.

• an upstream catalyst forming step of bringing only an upstream region of the honeycomb structure into contact with a catalyst component to form a catalyst;
• and
• a downstream catalyst forming step of bringing only a downstream region of the honeycomb structure into contact with a catalyst component to form a catalyst, the catalyst component having a lower concentration than the catalyst component for the upstream region.
