A honeycomb filter including a catalyst-carrying article, and an outer peripheral coat layer disposed on an outer peripheral face of the catalyst carrying article, wherein an amount of the catalyst loaded in the outer peripheral coat layer at a position 50 μm or more apart from a boundary face between the catalyst-carrying article and the outer peripheral coat layer is 5 mass % or less when a measurement piece having a cross section where a boundary portion between the catalyst-carrying article and the outer peripheral coat layer can be observed and being obtained by embedding a resin in the boundary portion in the cross section is measured by an energy dispersive fluorescent X-ray analysis using a scanning electron microscope. |
