PROBLEM TO BE SOLVED: To appropriately read identification information stamped on a surface of a steel material.SOLUTION: An identification information reader 1 includes: an application unit 30 applying a coating agent D onto a stamped surface 11 of a steel material 10 on which identification information 12 is stamped; an illumination unit emitting light onto the stamped surface 11 onto which the coating agent D is applied; an imaging unit 31 imaging the stamped surface 11 irradiated with the light; and an image processing unit 38 reading the identification information 12 from an image of the stamped surface 11 obtained by the imaging unit 31. The application unit 30 continuously applies the coating agent D onto the stamped surfaces 11 of a plurality of steel materials 10 during transport. The imaging unit 31 continuously images the stamped surfaces 11 of the steel materials 10 during transport. 【課題】鋼材の表面に刻印された識別情報を適切に読み取る。【解決手段】識別情報読取装置１は、識別情報１２が刻印された鋼材１０の刻印面１１に塗布剤Ｄを塗布する塗布部３０と、塗布剤Ｄが塗布された刻印面１１に対して光を照射する照明部と、光が照射された刻印面１１を撮像する撮像部３１と、撮像部３１で撮像された刻印面１１の画像から識別情報１２を読み取る画像処理部３８と、を有する。塗布部３０は、搬送中の複数の鋼材１０の刻印面１１に塗布剤Ｄを連続的に塗布する。撮像部３１は、搬送中の複数の鋼材１０の刻印面１１を連続的に撮像する。【選択図】図１
