MULTI-LAYER THIN PLATE MOLDED PRODUCT WITH CARBONACEOUS MATERIAL LAYER AND MANUFACTURING METHOD THEREOF

To provide a multi-layer thin plate molded product with a carbonaceous material layer using an ultra-quenching transition control injection method that can obtain a high-quality, much thicker plate material compared to a quenching foil band by a conventional manufacturing technology, and having excellent conductivity, lamination strength, corrosion resistance, durability, etc.SOLUTION: In a multi-layer thin plate molded product, a thin plate-shaped metal matrix having a fine three-dimensional surface shape having an uneven portion having a desired height and width is used as a substrate, and a passivation layer surface layer region exists on the front end surface of the substrate, and a part of a conductive A film has an exposed portion on the surface so as to penetrate the passivation layer surface layer and conduct with the metal matrix under the passivation layer surface layer region, and on the back surface of the substrate facing the front end surface of...
