    摘要: In a honeycomb filter 20, a catalyst is loaded on partition portions 22 and trapping layers 24 such that the catalyst amount A at a partition-intersecting portion 32 is smaller than the catalyst amount B at a partition central portion 34. The ratio A/B of the catalyst amount A to the catalyst amount B is preferably 0.30 or more and 0.90 or less. The catalyst is loaded such that the catalyst amount C at a trapping layer corner 36 is smaller than the catalyst amount D at a trapping layer central portion 38. The ratio C/D of the catalyst amount C to the catalyst amount D is preferably 0.80 or more and 0.95 or less.
