Abstract
A yarn which is configured by using expanded graphite and polytetrafluoroethylene (PTEE) is provided while improving the yarn so that the expanded graphite functioning as a core member is not exposed and it can be simply produced. The yarn is formed by: forming a base member configured by enveloping an expanded graphite sheet member with a PTEE film, in a state where the PTEE film and the expanded graphite sheet member are aligned with each other in longitudinal direction; and twisting the base member. The base member has an approximately circular sectional shape, and is configured by enveloping the expanded graphite sheet member having a rounded sectional shape with the PTEE film which is rounded in a pipe-like shape.
