    • There is provided a honeycomb filter including: a honeycomb base material; plugged portions; and a porous collecting layer disposed on the surface of the partition wall parent material in at least the remaining cells. The collecting layer has a constitution in which a plurality of particles combine or intertwine with one another, and the collecting layer includes flat plate-like particles as the plurality of particles. The plurality of particles are particles in which an average long diameter is 0.2 μm or larger and smaller than 10 μm, an average value of ratios (long diameters/short diameters) of the long diameters to the short diameters of the respective particles is smaller than 3, and an average value of ratios (the long diameters/thicknesses) of the long diameters to thicknesses of the respective particles is 3 or larger. An open area ratio of the surface of the collecting layer is 10% or larger.
    • 提供一种蜂窝过滤器,其包括:蜂窝状基材; 堵塞部分 以及在至少剩余的单元中设置在分隔壁母材的表面上的多孔收集层。 收集层具有多个颗粒彼此结合或缠绕的构造,并且收集层包括作为多个颗粒的平板状颗粒。 多个粒子是平均长径为0.2μm以上且小于10μm的粒子,长径与各粒子的短径的比(长径/短径)的平均值小于 3,长径与各粒子的厚度的比(长径/厚度)的平均值为3以上。 收集层的表面的开口率为10%以上。
