To provide a molten metal feeding device and a molten metal feeding method capable of preventing the occurrence of turbulent flow of molten metal and the entrapment of air into the molten metal at the time of feeding the molten metal.

A nozzle part 10c is arranged at the tip end of a pipe part 10b so that the center axis Q of the nozzle part 10c inclines by angle α (0°≤α≤30°) to the center axis P of the pipe part 10b in the case of projecting the pipe part 10b and the nozzle part 10c on the perpendicular surface. The pipe part 10b, the nozzle part 10c and a die casting sleeve 20 are arranged so that α2≥α1 is satisfied, thereby allowing the molten metal to smoothly flow out of a molten metal feed hole 10d, and suppressing the occurrence of the turbulent flow of the molten metal flowing out of the molten metal feed hole 10d.
