ABSTRACT:
There is disclosed a fluid filtration element having a porous core cylinder, a sectionally thick filtration cylinder fitted around the core cylinder, and end plates secured to the end surfaces of filtration cylinder. Highly densified portions are formed at the filtration cylinder ends to which the end plates are press-fitted, thereby hindering the fluid permeation. Sectionally thin protrusions erected on the end plate surfaces are cut into the highly densified portions.
