    • PROBLEM TO BE SOLVED: To provide a piercing plug equipped with a sprayed coating which is hard to peel off.SOLUTION: A method for producing a piercing plug equipped with a sprayed coating includes a step of preparing a piercing plug on the surface of which a sprayed coating containing iron and iron oxide is formed, and a heat treatment step of holding the piercing plug for 5-60 minutes at 400-550°C. When the heat treatment temperature is 400°C or more, the transformation from wustite to magnetite is promoted, and an iron ratio and a magnetite ratio in the sprayed coating increase. If the heat treatment temperature is 400°C-550°C, the magnetite ratio and the iron ratio which improve the adhesiveness with the plug body are raised in the sprayed coating. Further, tensile residual stress in the sprayed coating becomes low.
