The method of manufacturing a bonded wafer including, implanting hydrogen ions, rare gas ions, or a mixture of hydrogen ions and rare gas ions into a bond wafer to form an ion implantation layer in the bond wafer, bonding the bond wafer in which the ion implantation layer has been formed to a base wafer to form a bonded wafer, and subjecting the bonded wafer to heat treatment to separate the bond wafer from the base wafer at the ion implantation layer as boundary to form the bonded wafer. In the method of manufacturing a bonded wafer, the heat treatment at least from the start of the separation to the end of the separation is conducted in an oxidizing atmosphere.
