1. A fiber structure manufacturing apparatus, comprising:
a defibration unit that pulverizes and defibrates a raw sheet material that contains fibers;
a transportation unit that transports a defibrated material after defibration by the defibration unit;
a forming unit that forms a fiber structure from the defibrated material transported by the transportation unit;
a temperature acquisition unit that acquires a temperature inside the defibration unit; and
a control unit that controls a mass flow of gas that contains the defibrated material transported from the defibration unit in accordance with the temperature acquired by the temperature acquisition unit.
