Provided are a fuel tank made of polyketone and a method of manufacturing the same. The method includes injection-molding an upper cover and a lower cover using an injection-molding machine, placing the upper cover and the lower cover at a relatively high position and a relatively low position, respectively, assembling the upper cover and the lower cover with each other, and bonding contact surfaces between the upper cover and the lower cover to each other using a laser beam. Since the upper cover and the lower cover are formed at the same time and are bonded to each other immediately after being assembled by a machine, it is possible to achieve automated production, mass production and remarkable cost reduction. Further, since the fuel tank has sufficient rigidity due to the rigidity of polyketone without an additional reinforcing member, it is possible to manufacture a lightweight fuel tank. |

Improved moisture absorption solder heat resistance is obtained in producing a metallic foil laminate body having a metal foil attached on both sides of a laminated base material including a plurality of insulating base materials. A laminated base material (2) is first prepared by pressurizing and integrating a plurality of insulating base materials (2a) in a prepressing step. Then, the laminated base material (2) is heat-treated. Thereafter, this laminated base material (2) is sandwiched between a pair of metal foils (3A) and (3B), and heated and pressurized to be integrated into a metallic foil laminate body. The prepressing step makes it possible to prevent an interface between the insulating base materials (2a) from being generated. As a result, swelling is not generated on the surfaces of the insulating base materials (2a). |
