To provide a bar magnet structure in a foreign matter elimination apparatus stored in the foreign matter elimination apparatus for magnetically attracting and eliminating a magnetic substance from a material and a product mixed with the magnetic substance.

A bar magnet 1 of the bar magnet structure in the foreign matter elimination apparatus comprises the one in which a magnetic field part 2 comprising a magnet 4 or the like and a non-magnetic part 3 connected thereto are integrally connected. The bar magnet 1 can completely remove/eliminate the magnetic substance magnetically attached to the magnetic field part 2 by scraping the non-magnetic part 3 with the magnetic part 2.
