A ceramic filter is provided including a substrate, a separation layer comprising titania and having an average pore size in a range of 0.08 to 1 .mu.m and a thickness in a range of 5 to 20 .mu.m, and an intermediate layer formed between the substrate and the separation layer. The intermediate layer includes aggregate particles that are bonded together with glass frits, and aggregate particles of the intermediate layer are smaller than aggregate particles of the substrate and larger than aggregate particles of the separation layer.
