Abstract
The sheet manufacturing apparatus in the present invention includes a defibration unit configured to cause a rotating unit to rotate and dry-defibrating a defibration object, and at least a part of defibrated material that has been dry-defibrated is deposited and heated to manufacture a sheet. A plurality of rotating plates provided with a base section located on a central rotation axis side and a plurality of protruding sections that protrude out in a direction drawing away from the central rotation axis are stacked in the rotating unit such that the protruding sections are in contact in a direction in which the central rotation axis extends.
