A honeycomb filter 1 is constituted by integrating a plurality of honeycomb segments 12 including a large number of through channels 3 partitioned by partition walls 2 and extending through an axial direction. The honeycomb filter 1 is characterized in that a thermal conductivity, strength, or strength/Young's modulus ratio of a honeycomb segment 12 <SUB>I </SUB>disposed in a central portion is high, or a porosity, average pore diameter, or (porosityx(average pore diameter)<SUP>2</SUP>) of a wall portion is small with respect to a honeycomb segment 12 <SUB>O </SUB>disposed in an outer peripheral portion. The honeycomb filter is used in a filter or the like for capturing particulates in an exhaust gas, superior in regeneration efficiency, and capable of simultaneously achieving durability and low pressure loss.
