A method for manufacturing an optical recording medium, comprising:
- forming a first transparent film layer forming base material by bonding a first transparent film layer to one of principal surfaces of a first base material with a first adhesion layer therebetween;
- forming a second transparent film layer forming base material by bonding a second transparent film layer to one of principal surfaces of a second base material with a second adhesion layer therebetween;
- forming a recording material layer including a hologram recording material between a principal surface of the first transparent film layer forming base material adjacent to the first transparent film layer and a principal surface of the second transparent film layer forming base material adjacent to the second transparent film layer;
- forming, after the recording material layer is formed, a member having the recording material layer formed between the first transparent film layer and the second transparent film layer by de-bonding a first adhesion interface between the first transparent film layer and the first adhesion layer and de-bonding a second adhesion interface between the second transparent film layer and the second adhesion layer;
- and
- bonding the member to one of principal surfaces of a base plate.
