Abstract:
1. A method for manufacturing a decorative material, comprising: a first process to form a metallic oxide layer made from aluminum oxide on a first principal surface of a support substrate having the first principal surface and a second principal surface that face toward each other; a second process to form a radio wave permeable metallic layer containing at least one type to be selected from the group consisting of Sn and In as a structural component on the metallic oxide layer; a third process to form a mask layer containing a synthetic resin on a portion of the radio wave permeable metallic layer; a fourth process to apply etching to a portion where no mask layer is formed, and to form a pattern of the radio wave permeable metallic layer and that of the metallic oxide layer to be roughly the same as that of the mask layer, viewing from a roughly-normal direction of the principal surface of the support substrate; and a fifth process to form an adhesive layer containing a synthetic resin on the mask layer.
