The invention claimed is: 1. A sheet manufacturing apparatus comprising: a first sieve that has a first opening for screening a defibrated material that is defibrating-processed; a second sieve that has a second opening having a size equal to or greater than a size of the first opening and refines the defibrated material passing through the first sieve by causing the defibrated material to pass through the second opening; and a belt on which the defibrated material passing through the second sieve is deposited. 2. The sheet manufacturing apparatus according to claim 1 , wherein the size of the second opening is greater than the size of the first opening. 3. The sheet manufacturing apparatus according to claim 1 , wherein the size of the second opening is equal to the size of the first opening. 4. The sheet manufacturing apparatus according to claim 1 , wherein an upper limit of the size of the second opening is 5 mm. 5. The sheet manufacturing apparatus according to claim 1 , wherein the first sieve has a cylindrical shape on which the first opening is formed. 6. The sheet manufacturing apparatus according to claim 1 , wherein the second sieve has a cylindrical shape on which the second opening is formed. 7. The sheet manufacturing apparatus according to claim 1 , further comprising: a feeder which supplies a resin to a path in which a passed material passing through the first sieve is directed to the second sieve.
