To provide a porous ceramic filter whose collection efficiency for PM (Particulate Matter) is not degraded even when it is repeatedly used, moreover, in which pressure loss due to DPF (Diesel Particulate Filter) is hardly caused and has vibration resistance and thermal shock resistance.

A honeycomb shape filter and the manufacturing method thereof are characterized in that ceramic nanotube is contained by at least 0.5 wt.% in sintered porous ceramic material in the filter made of porous ceramic material. The ceramic nanotube is preferably the sintered body of a non-metallic inorganic compound which contains at least one element selected from the group consisting of carbon, nitrogen and silicon.
