Abstract

A sheet manufacturing apparatus includes: a defibration unit that defibrates a raw material containing fibers in a gas atmosphere; and a sheet former that forms a sheet by using at least a part of defibrated substances obtained through a defibrating process performed by the defibration unit. The defibration unit and the sheet former are thermally blocked from each other.
