Claims

[Scope of Claim for Utility Model Registration] (1) In a filter cartridge constructed by providing a unit member by sealing microporous membranes on both sides of a membrane support having a central opening, and laminating a plurality of unit members. The periphery of the central opening of each unit member is welded and laminated, and engaging portions are provided on the outer periphery of each unit member, and the joining core material is engaged with these engaging portions to melt and join, and at the same time, each unit member is bonded to each other. A laminated type filter cartridge made of fluororesin, characterized by being melt-bonded. (2) The filter cartridge according to claim 1, wherein a protrusion is provided on the outer peripheral edge of the membrane support, and a groove is formed in the protrusion to serve as an engaging portion. (3) Claim 1, wherein the membrane support is formed into a disk shape;
Or the filter cartridge according to 2. (4) The microporous membrane is made of PTFE and has a maximum pore diameter of 0.
．． 4. The filter cartridge according to claim 1, wherein the filter cartridge has a diameter of 01 to 2μ. (5) The membrane support and bonding core material are PFA, EPE,
FEP, ECTFE, PCTFE, ETFE, P
5. The filter cartridge according to claim 1, wherein the filter cartridge is made of a thermoplastic fluororesin such as VDF.
