<P>PROBLEM TO BE SOLVED: To join members made of a polylactic acid with a polylactic acid. <P>SOLUTION: The method for joining the biodegradable resin members comprises a step for arranging an adhesive sheet comprising the polylactic acid between two members of the biodegradable resin to be joined, and heating the arranged sheet to a temperature equal to or higher than the glass transition temperature of the polylactic acid constituting the adhesive sheet, and equal to or lower than the melting point while pressurizing the sheet. The members of the biodegradable resin to be joined are constituted of a crystallized polylactic acid, or a composite of the crystallized polylactic acid and a biodegradable fiber, and an amorphous polylactic acid is used as the polylactic acid constituting the adhesive sheet. <P>COPYRIGHT: (C)2004,JPO |
