A method for manufacturing spoon and chopstick using magnesium alloy sheets is provided to improve formability and machining accuracy by employing hot-drawing method by a press. A method for manufacturing spoon and chopstick using magnesium alloy sheets comprises a step of supplying flat magnesium alloy sheets to a press, a step of pressing the magnesium alloy sheets to the die of the press to keep it in position, a step of making spoon and chopstick through hot-drawing of the magnesium alloy sheets by operating the press to close the punch and the die at the same time as heating the punch and the die, and a step of providing gloss effect to the spoon and chopstick by plating the surface of the spoon and chopstick. The magnesium alloy sheet is composed of magnesium 96.3~97.3 weight%, aluminum 2.4~3.0 weight%, and zinc 0.3~0.7 weight%.
