PROBLEM TO BE SOLVED: To provide a filter cartridge which enables less dissolution of unnecessary ions into a liquid being filtered out. SOLUTION: The filter cartridge to be installed in a casing of a filtering device for filtering a liquid is constituted of a cylindrical outer tube 41 having a plurality of holes disposed on its peripheral surface through which a liquid passes, a cylindrical inner tube 43 having a plurality of holes disposed on its peripheral surface through which a liquid passes and coaxially disposed with the outer tube 41, a pair of end caps 45 and 46 each disposed on either axial end of the outer and inner tubes 41 and 43 blockading the axial end faces of a filtration space RK formed between the outer and inner tubes 41 and 43, a filter medium 47 with which the filtration space RK is filled, and disc gaskets 48 and 49 each having a coaxial hole and each detachably installed on the outer surfaces of the end caps 45 and 46 respectively. Each of the gaskets 48 and 49 is held by four claw-shaped members 67 coaxially outwardly extending from the end cap 45 or 46 with the claw-shaped members 67 hooked on the inner peripheral surface of the gasket hole.
