Claims

[Claims for Utility Model Registration] [Paragraph 1] (a) A relatively wide and long main filter plate is provided with liquid passage holes 12 in a straight line at appropriate intervals over substantially the entire length in the longitudinal direction thereof, (b) Each liquid passage hole 1 on one side of this main filter plate.
(c) A main filter plate with narrow spacer filter plates having liquid passage holes 14 communicating with the main filter plates arranged in a straight line at appropriate intervals and approximately the same length as the main filter plate; A filter plate is wound around the outer periphery of the core tube to form an element of a desired diameter, (d) the element has both of the liquid passage holes 12, 1;
4 are connected to form a plurality of radial liquid passages 16, and these liquid passages 16 are made to communicate with a through hole 17 provided on the outer periphery of the core cylinder, (e) a main body exposed on the outermost periphery of the element A liquid filter body characterized in that a band-shaped sealing material for closing the liquid passage holes 12 is wound around the liquid passage holes 12 of the filter plate in a row. [Claim 2] The liquid filtration according to claim 1, wherein the longitudinal diameter of both liquid passage holes 12 and 14 in the group row direction is formed to be larger than the length between the liquid passage holes 12 and 14. body.
