PROBLEM TO BE SOLVED: To provide a ceramic filter which is equipped with an NF membrane or a UF membrane and can reduce the number of calcination times to reduce manufacturing cost, and a method of manufacturing this ceramic filter. SOLUTION: The ceramic filter comprises a substrate 111 obtained by sintering substrate particles Q<SB>ij</SB>having an average particle diameter of 2-60μm, and a gap filling layer 141 embedded to a certain depth from the upper part of the substrate 111 and filling gaps between the substrate particles Q<SB>ij</SB>with gap filling particles Q<SB>rs</SB>having an average particle diameter 1/10-1/7 times that of the substrate particles Q<SB>ij</SB>.
