PROBLEM TO BE SOLVED: To improve metallic foil productivity by effectively reducing extrusion ratio. SOLUTION: In an extrusion molding device 10 for extrusion molding a metallic foil 44 via slits 18 formed on a die 20 by pressing a billet 24 inputted in a hollow part 14 of a container 16 towards the die 20 side with a stem 26, a length of the slit 18, winch defines a metallic foil 44 width, is constituted larger than the hollow part 14 diameter. In this case, the above slits 18 are formed on the die 20 at outer positions rather than a position corresponding to the hollow part 14 of the container 16 so that the hollow part 14 and the slits 18 are connected through via connecting passages 34.
