PURPOSE: Biodegradable filters for filtering fluid is provided to enhance the lifetime of the filter and improve a filtering effect by increasing a lamination density of non-woven fabric of an outer filtering member compared with an inner filtering member. CONSTITUTION: Biodegradable filters for filtering fluid comprises a filtering member(110). The filtering member is elongated in one direction to form a hollow(130) for which both ends are open by comprising a non-woven fabric covering having a certain thickness. The non-woven fabric comprises at least one of a degradable resin of polylactic acid, polyglycolic acid, polycaprolactone, aliphatic polyester resin, polyhydroxybutyric, D-3-hydroxybutyric acid, poly(butylene succinate), poly(butylene succinate)-(0036)-co-adipate, and poly(butylene succinate fumaric).
