Zusammenfassung:	To make it possible to easily and reliably obtain a plating removal part with respect to chiefly a steel material plated part on a face on which plural steel materials with a plated surface are overlapped.SOLUTION: According to the present invention, with respect to a plated part 18 of a steel material 19 with the plated part 18 on a face on which plural steel materials 19 are overlapped, the plated part 18 is partially removed or oxidized by heating so as to form a plating removal part 21.SELECTED DRAWING: Figure 6 【課題】主に、表面にメッキを施した鋼材の、鋼材を複数重ね合わせた面のメッキ部に対して、容易且つ確実にメッキ除去部が得られるようにする。【解決手段】メッキ部１８を有する鋼材１９の、鋼材１９を複数重ね合わせた面のメッキ部１８に対し、加熱によってメッキ部１８を部分的に除去または酸化させてメッキ除去部２１を形成するようにしている。【選択図】図６
