To provide a molding method of a double-layer plastic sheet in which a plastic sheet such as a color sheet or a functional sheet is laminated on an upper layer.SOLUTION: There is provided a molding method of a double-layer plastic sheet in a molding of the double-layer plastic sheet is configured in that: on a surface of a base resin 11c that is extruded flatly from a T-die 11a, a laminated plastic sheet 21a, such as a plastic color sheet or a plastic flameproof sheet, which is compatible with the base resin 11c produced in a separate process is laminated to completely integrate a resulting sheet. There is also provided a molding method in which a special functional sheet 21b having a property such as heater function or magnetic function is wrapped inside the completely integrated two-layer plastic sheet.SELECTED DRAWING: Figure 1 【課題】上層にカラーシート又は機能性シートなどのプラスチックシートを積層した二層プラスチックシートの成形方法の提供【解決手段】二層プラスチックシートの成形において、Ｔダイ１１ａより扁平に押出されている基材樹脂１１ｃの表面に、別工程で生産された該基材樹脂１１ｃと相溶性のあるプラスチックカラーシート又はプラスチック防炎シートなどの積層プラスチックシート２１ａを、積層しながら完全に一体化する二層プラスチックシートの成形方法。また、完全に一体化された前記二層プラスチックシートの間に、ヒータ機能または磁性機能などの特殊機能シート２１ｂを包み込む成形方法。【選択図】図１
