A metal substrate includes a first insulating substrate, a second insulating substrate, a first metal layer, a second metal layer, and a release layer. The first insulating substrate has a first modifying surface, and a second surface facing the first modifying surface. The first metal layer faces the second surface. The release layer is attached to the first modifying layer. The second insulating substrate is attached to a side of the release layer to arrange the release layer in between the first modifying surface and the second insulating substrate. The second metal layer is arranged on a side of the second insulating substrate to arrange the second insulating substrate in between the release layer and the second metal layer. The distinct surface roughness of the first modifying surface practically has the change of 10% or less after separating the first modifying surface from the release layer. |
