PROBLEM TO BE SOLVED: To provide a high temperature filtration device absorbing expansion or contraction of a filter module mounting part by variation in temperature of a liquid to be treated and maintaining sealing property of a filter without damaging the filter module. SOLUTION: In the filtration device, the inside of a closed container is divided to a lower filtration chamber 7a and an upper treating liquid chamber 7b by a partition plate 6 and a plurality of filter modules 3 having openings at one side ends and fixed to the treating liquid chamber are supported by the partition plate and is hangingly provided in the filtration chamber. A support part 3b of the filter module is formed to a flange shape and a lower end of the flange-like part is engaged with a hole having a step of the partition plate. A filter support part engaged and pressed with a hole of a press plate 9 integrally provided on an upper part of the partition plate is provided. An inlet 4a for liquid to be treated is provided on the filtration chamber and a treating liquid outlet is provided on the treating liquid chamber. A member which can absorb thermal expansion at rise of temperature and thermal contraction at drop of temperature of the filter support part generated by variation in temperature of the liquid to be treated is provided on the filter support part.
