PROBLEM TO BE SOLVED: To provide a filtration apparatus capable of surely replacing a filter paper with impurities deposited thereon with an unused or almost unused filter paper without substantially lowering a filtering flow of unfiltered liquid passing therethrough, when impurities of a certain amount or higher have attached on the filter paper. SOLUTION: This filtration apparatus 11 for filtering unfiltered liquid flowing into a storage tank 12 by passing through a belt-like filter paper 10, and discharging filtrate from the storage tank 12 is provided with a filter paper sending mechanism part 14 which holds a part of the filter paper 10 provided in the storage tank 12 for passing through unfiltered liquid, has an annular net belt 26 allowing filtrate to pass therethrough, and can transfer the filter paper 10 by running the annular net belt 26.
