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. 【課題】被解繊物を解繊する解繊部を有し、当該解繊部において、繊維長を短くしすぎることなく解繊し、実用的な強度を有するシートを製造することのできるシート製造装置を提供する。【解決手段】本発明に係るシート製造装置は、回転部を回転させて被解繊物を乾式解繊処理する解繊部を含み、乾式解繊処理された解繊物の少なくとも一部を堆積させて加熱してシートを製造するシート製造装置であって、前記回転部は、回転中心側に位置する基部と、前記基部から前記回転中心から離れる方向に突設する複数の突部とを備える複数の回転プレートを、前記回転中心の延びる方向において前記突部が接するように積層する。【選択図】なし
