PROBLEM TO BE SOLVED: To provide a method for regulating the compressibility of an expanded graphite sheet capable of regulating the compressibility of an expanded graphite sheet without depending on density.SOLUTION: The method for regulating the compressibility of an expanded graphite sheet is characterized in that an expanded graphite sheet is subjected to heating treatment in a nonoxidizing atmosphere, and its compressibility is changed in accordance with at least either heating temperature or heating time. It is desirable that, when the heating temperature conditions in the heating treatment are controlled to 900 to 1,350°C, since the compressibility can be effectively changed without performing the heating too much. Further, it is desirable, when, in the heating time conditions in the heating treatment 2 to 8 hours are used as one unit, since the compressibility can be finely adjusted by performing the heating treatment a plurality of times.
