Abstract
An expanded graphite sheet is provided that can remarkably improve the quality and yield rate by preventing chipping and cracks in the surface in molding the sheet into a desired shape by inhibiting degradation in the flexibility while reducing the ash content to a certain degree. An expanded graphite sheet () has a flexibility of 25 times or greater, as determined in a flexibility test in which the flexibility is defined as the number of times the expanded graphite sheet () can be bent using a flexibility testing device having a rotator () to which one end of a plate-shaped expanded graphite sheet () is fixed, a weight () fixed to the other end of the expanded graphite sheet (), and a bending position determining member () for determining a bending position of the expanded graphite sheet () when the rotator () is rotated.
