A magnetic separation device, with streamlined construction and heightened rate of magnetic adhesion, has two rotating plates 7, 8 which are fixed to a rotation axis and rotate while immersed in a liquid, and magnets 13 mounted on the rotating plates 7, 8. The magnetic separation device is constructed such that magnetic material in the liquid magnetically adheres to the rotating plates 7, 8 and is separated. Further, the magnetic separation device includes a yoke 14, surrounding and accommodating magnets, and having an aperture facing one of the magnetic poles; the yoke 14 has an aperture side face 14c which is in contact with the rotating plates 7, 8; and the aforementioned magnetic pole is in contact with the rotating plates 7, 8. Pairs of magnets 13 are arranged such that opposite magnetic poles oppose each other across the two rotating plates 7, 8, and a magnetic space is formed between the two magnetic plates 7, 8.
