A cartridge filter comprises a pleat-type porous membrane having a longer length than an effective filtering surface thereof; upper and lower end plates; a plurality of segmented cylindrical core members disposed between the upper and lower end plates; and protective caps for fastening and sealing an upper and lower reminder of the pleat-type porous membrane other than the effective filtering surface thereof. Each of said end plates is provided with a plurality of fins, each of which is covered by the pleat-type porous membrane. The pleat-type porous membrane is folded at each corner of respective end plates and fastened firmly between the end plate and the protective cap by melting means, adhesion or sealing means. |
