A fine particle collecting filter includes a honeycomb structure in which a plurality of honeycomb segments are integrally joined by a joining material, and has a constitution where an exhaust gas allowed to flow from an inlet end surface into cells passes partition walls, and then flows out from an outlet end surface to the outsides of the cells. The partition walls are made of a material containing SiC as a main component, at least one of an average open diameter of pores of an inlet side of the exhaust gas passing the partition wall and an average open diameter of the pores of an outlet side of the exhaust gas passing is from 0.1 to 5 μm, an average pore diameter of the whole partition wall is from 10 to 30 μm, and a thermal conductivity of the partition walls at room temperature is from 80 to 110 W/mK.
