PROBLEM TO BE SOLVED: To provide a filter element which is compact, has excellent water permeability and is used suitably in process equipment in a field such as chemical industries and food industries, in domestic water purifier or in other fields and to provide a method for manufacturing the filter element. SOLUTION: This filter element 1 consists of a porous body having a plurality of cells 9 through which an original liquid passes. At least one groove 4 is formed on one end 3a of the element 1, which has the prescribed depth from the end face 6a of the end 3a toward the inside and is extended almost linearly along the array of the prescribed cells 9 from one position on the edge of the face 6a to the other position to keep a diametral or chordal shape on the face 6a. A sealing material 5 is embedded from the face 6a to the depth shallower than the prescribed depth of the groove 4. A through-hole 7 is formed on the outer peripheral surface 2 of the element 1 by the groove 4 and the material 5, which is parted from the face 6a at the prescribed distance and penetrates the element 1 almost linearly from one position to the other position.
