Abstract:
1. A laminated substrate manufacturing method for manufacturing a laminated resin substrate by laminating and pressing a resin-metal foil, wherein said resin-metal foil is planar, has a first side longer than a second side, and includes a resin layer formed on a metal foil, on a planar core substrate such that a resin layer side of the resin-metal foil contacts the planar core substrate, the method comprising: laminating said resin-metal foil on said planar core substrate while opposing the resin layer side of said resin resin-metal foil to a side of said planar core substrate; bringing a flat metal plate portion of a buffer structure, said buffer structure formed by laminating a flat metal plate and a planar buffer member having a first side longer than a second side, into contact with a surface of said resin-metal foil on which a resin layer is not formed; and pressing said resin-metal foil against said planar core substrate by applying pressure on said planar buffer member in said buffer structure, wherein said planar buffer member is disposed on said resin-metal foil with said metal plate between in such a way that the first side and the second side of the said planar buffer member are aligned with the first side and the second side of said resin-metal foil, the lengths of the said first side and said second side of said planar buffer member are equal to or shorter than the lengths of said first side and said second side of said resin-metal foil respectively, said flat metal plate brought into contact with the resin-metal foil has a larger surface area than a surface area of the surface of said resin-metal foil on which a resin layer is not formed, and an area of said flat metal plate corresponding to an edge of said resin-metal foil is unobstructed by the buffer on a side contacting the buffer and is moveable in a direction opposite to which the buffer presses the metal plate upon receipt of force from said edge of said resin-metal foil.
