Abstract: A heat-resistant laminated sheet including an electrically conducting sheet (3) and a silicone resin layer (5) of a thickness of not less than 20 ?m formed on one surface of the electrically conducting sheet (3). The sheet has a laminar structure in which a layer of a silicone resin is formed on one surface of a metal foil (electrically conducting sheet), and is suited for use with the IH cooking devices.

Abstract: A structural body has an inner layer formed of a resin which does not transmit light with a specific wavelength, an outer layer stacked on the inner layer and formed of a resin which transmits the light with the specific wavelength, and a fine periodic structure provided on at least part of a surface of the inner layer facing the outer layer and having a plurality of photodecomposition generated convex and concave portions. The plurality of convex and concave portions of the fine periodic structure is formed alternatively, and horizontally and vertically with substantially equal intervals in between along the surface of the inner layer facing the outer layer.

Abstract: Laser marking is surely conducted on the second and subsequent layers of a structural body with a multilayer structure, whereby a marked part can be prevented from being marred, fouled, falsified or erased, as well as marking can be conducted in a variety of colors. A structural body 10 including an inner layer 12 and an outer layer 11 stacked, wherein said inner layer 12 is formed of a resin which does not transmit light with a specific wavelength and said outer layer 11 is formed of a resin which transmits light with the specific wavelength, and a fine periodic structure 14 in the form of convexes and concaves formed by generation of photodecomposition is provided on at least part of the surfaces 13 of the inner layer 12 which is opposite to the outer layer 11.
