CERAMIC FILTER

There is provided a ceramic filter formed on a porous base material and having satisfactory transmission amount and selectivity. The ceramic filter has a first surface dense layer 3 having an average pore diameter of 0.1 to 3 µm on an alumina porous base material 2 having an average pore diameter of 1 to 30 µm, a second surface dense layer 4 having an average pore diameter of 0.01 to 0.5 µm on the first surface dense layer 3, and a third surface dense layer 5 made of a titania sol and having an average pore diameter of 0.3 to 20 nm on the second surface dense layer 4. Moreover, on the third surface dense layer 5, a carbon membrane layer 6 as a molecular sieve carbon membrane is formed.
