PROBLEM TO BE SOLVED: To provide a sheet production apparatus including a fibrillation unit for fibrillating an object to be fibrillated, and producing a sheet having a practical strength by fibrillation without excessively reducing a fiber length in the fibrillation unit.SOLUTION: A sheet production apparatus includes a fibrillation unit in which an object to be fibrillated is subjected to a dry type fibrillation treatment by rotating a rotation unit. At least, a part of the object to be fibrillated, subjected to the dry type fibrillation treatment, is accumulated and heated to produce a sheet. In the rotation unit, a plurality of rotation plates each having a base part located at the side of a rotation axis and a plurality of protrusions protruded from the base part in a direction away from the rotation axis, are laminated so that the protrusions come in contact with each other in an extending direction of the rotation axis. |
