Abstract
The present invention addresses a problem of providing a grease composition that uses hydrophilic nanofibers but still has excellent water resistance and does not readily experience oil separation. The grease composition contains a base oil, hydrophilic nanofibers having a thickness (d) of 1 to 500 nm, and an organic bentonite.
