(57) [Summary] (Modified) [Purpose] Hydrophilic PTF without impairing the porous structure, which is important for the characteristics of the PTFE porous body, in the adhesion of tetrafluoroethylene resin (PTFE) porous bodies to each other. E To provide a bonding method applicable to a porous body. [Structure] A method for adhering PTFE porous bodies to each other, A thermoplastic resin having a melting point of 250 ° C. or lower is disposed between the portions of the PTFE porous body to be bonded to each other, and then at a temperature of the melting point of the thermoplastic resin or higher and 250 ° C. or lower, A method for adhering a PTFE porous body, in which a molten thermoplastic resin is caused to enter the porous space of the PTFE porous body by pressing the portions to be adhered from both outsides. |
