Abstract
A sheet manufacturing apparatus includes a web forming unit configured to form a web which includes fibers and resin, and a first pressurizing unit and a second pressurizing unit configured to pressurize the web. The first pressurizing unit has a separation layer, is positioned on an upstream side of the second pressurizing unit in a transfer direction of the web, and is configured to heat the web. The second pressurizing unit is positioned on a downstream side of the first pressurizing unit in the transfer direction of the web, does not have a separation layer, and is configured not to heat the web. The pressurizing force from the first pressurizing unit is smaller than the pressurizing force from the second pressurizing unit.
