PROBLEM TO BE SOLVED: To provide a dust collecting ceramics filter the pressure loss of which is restrained during dust collecting operation, the performance of which can be restored to the initial state by backwashing under pressure and by which the dust contained in the combustion gas (including exhaust gas) of heavy oil, coal, waste or the like can be satisfactorily collected. SOLUTION: This multi-layered dust collecting ceramics filter, which is constituted of a supporting body consisting of a porous ceramics and a filter layer, has spherical ceramics particles stuck on the surface of the supporting body by using an inorganic binder of 8 wt.% or smaller.
