PURPOSE:To obtain a liquid separation apparatus excellent in heat resistance and chemical resistance generating no liquid stagnation and capable of reducing the flow amount of a raw liquid, by laminating a filter unit wherein two filter bodies each comprising a ceramics porous body are inserted in a support frame so as to form a space therebetween. CONSTITUTION:A filter unit 5 is formed by inserting filter bodies 1, 2 each comprising a ceramics porous body obtained by sintering a fine particles comprising alumina in a flat plate shape in a support frame 4 in such a state that spacers 3 comprising rubber are placed between said filter bodies 1, 2 and a large number of the filter units 5 are laminated between a fixed side end plate 6 and a movable side end plate 8 and integrated under pressure. The raw liquid from a raw liquid supply pipe 19 is flowed in the spaces 9 between the filter bodies 1, 2 or the spaces outside the filter bodies 1, 2 to be filtered by the filter bodies 1, 2 and only the transmitted liquid is taken out from the spaces in the opposite side through communication ports 18. The remainder of the raw liquid is flowed out to the raw liquid outflow ports 16 of a support frame 5 through communication parts 17 to be supplied to the other filter unit 5 separated by an intermediate plate 20.
