- the method of sticking the resin layer 22 on the substrate 30 in a peelable manner may be a known method.
- the resin layer 22 and the substrate 30 may be pressure-bonded using a roll or a press. It is preferable because the resin layer 22 and the substrate 30 are more closely adhered by pressure bonding with a roll or a press. Further, it is preferable because bubbles mixed between the resin layer 22 and the substrate 30 are relatively easily removed by pressure bonding with a roll or a press.
- the surfaces of the resin layer 22 and the substrate 30 that are in contact with each other are sufficiently washed and laminated in a clean environment. Even if foreign matter is mixed between the resin layer 22 and the substrate 30, the resin layer 22 is deformed and thus does not affect the flatness of the surface of the substrate 30, but the higher the cleanness, the better the flatness. Therefore, it is preferable.
