Abstract
A separation object including at least two types of resins with different glass transition temperatures (glass transition temperature of a first resin 1<glass transition temperature of a second resin 2) is placed on a separating member 3. Next, primary heating is applied at a temperature between the glass transition temperatures of the first resin 1 and the second resin 2, and pressurization is additionally performed to cause the first resin 1 to adhere to the separating member 3. Subsequently, a heat history of secondary heating at a temperature higher than the primary heating temperature is applied to detach and recover the second resin 2 by restoring the shape of the second resin 2, while the first resin 1 adhering to and retained by the separating member 3 is detached by a blade 5 and the like for recovery.
