    Abstract: A manufacturing method includes stacking, between two endless belts, a first sheet of metal foil, a plurality of insulating films, and a second sheet of metal foil in this order one on top of another and hot-press molding these sheets and films together to form an insulating layer out of the plurality of insulating films. Each of the plurality of insulating films has a first surface and a second surface. The second surface has a larger ten-point mean roughness (Rzjis) than the first surface. The absolute value of difference between a ten-point mean roughness (Rzjis) of a surface, in contact with the first sheet of metal foil, of the insulating layer and a ten-point mean roughness (Rzjis) of another surface, in contact with the second sheet of metal foil, of the insulating layer is equal to or less than 0.35 ?m.

  • Publication number: 20120081878
    Abstract: In an image display apparatus used at a restaurant or the like, a storage portion for receiving articles such as a menu is separately provided as a dedicated part. Therefore, the number of parts increases, and an assembly operation, an installation operation, and the like cost much labor. An image display apparatus that requires no dedicated part and can reduce the number of parts for thereby simplifying an assembly operation, an installation operation, and the like can be obtained by unifying a support portion for supporting a display body and a storage portion.
