Abstract: A magnesium-based medical device which can adjust a degree of corrosion within a wide range of period such that the device can maintain a sufficient strength only during a desired period and disappears within a desired period thereafter and a manufacturing method thereof are provided. A magnesium-based medical device of the present invention is a magnesium-based medical device in which a base material is made of magnesium or a magnesium alloy, wherein a corrosion-resistant film is formed on a surface of the base material, and variation in surface hardness of the formed corrosion-resistant film in the in-plane direction is less than 21 in terms of a dispersion value of Vickers hardness.
