Provided is a piercer plug having further improved wear resistance. The piercer plug (10) is equipped with a plug body (11) and a sprayed coating film (12) formed on the surface of the plug body (11). The sprayed coating film (12) includes an iron-based alloy and an oxide thereof. The chromium concentration obtained by analyzing the sprayed coating film (12) by fluorescent x-ray analysis is 3-20% by mass. L'invention concerne un perceur-mandrineur ayant une résistance à l'usure davantage améliorée. Le perceur-mandrineur (10) est équipé d'un corps de bouchon (11) et d'un film de revêtement pulvérisé (12) formé sur la surface du corps de bouchon (11). Le film de revêtement pulvérisé (12) comprend un alliage à base de fer et un oxyde de celui-ci. La concentration en chrome obtenue par analyse du film de revêtement pulvérisé (12) par analyse par rayons x fluorescent est de 3 à 20 % en masse. 耐摩耗性をさらに高めたピアサープラグを提供する。ピアサープラグ（１０）は、プラグ本体（１１）と、プラグ本体（１１）の表面に形成された溶射皮膜（１２）とを備える。溶射皮膜（１２）は、鉄基合金及びその酸化物を含む。溶射皮膜（１２）を蛍光Ｘ線分析で分析して得られるクロム濃度が、３～２０質量％である。
