Abstract: The sheet manufacturing apparatus includes: a rough crushing unit that roughly crushes a raw material containing fibers; and a defibration unit that defibrates the roughly crushed raw material in a gas atmosphere. In addition, the sheet manufacturing apparatus includes: first and second web formers that accumulate defibrated substances obtained through a defibrating process and form webs; and a sheet former that forms a sheet of the second web. In addition, the sheet manufacturing apparatus includes: a vaporization-type humidifying unit that humidifies a space in which the raw material is roughly crushed by the rough crushing unit; and a mist-type humidifying unit that humidifies the webs that are formed by the first and second web formers.
