Abstract

Detection of contained metal contained in an article can be carried out with a high sensitivity with a simple operation in a limited space. A transmission coilthat generates a magnetic field for inspection from an upper surface side through a lower surface side of a placing tableand a plurality of magnetic sensorsfor detecting the magnetic field are provided in a headdisposed on a lower surface side of the placing tablefor placing an article which is an inspection object. When the headis scanned so as to cover the entire lower surface-side region of the placing table, metal being contained in the article placed on the placing tableis detected on the basis of a change in the magnetic field being detected by the magnetic sensors
