PROBLEM TO BE SOLVED: To provide a magnetic catcher that can be improved in attracting force without changing materials and sizes of permanent magnets. SOLUTION: The magnetic catcher has a plurality of permanent magnets 21 and 22 each of which is constituted by magnetizing a magnetic material formed in a rectangular parallelepiped or plate-like shape in the thickness direction, so that a pair of surfaces 20 of the material having the largest areas among six surfaces of the material form first and second magnetic poles S and N, and the substantial total of three or more magnetic yokes 14, 23, and 14 which are closely adhered to the pairs of surfaces 20 of the magnets 21 and 22, respectively. The magnetic catcher is also provided with the total of three or more magnetic poles 31, 32, and 31 formed on the outer edges of the yokes 14, 23, and 14, respectively, and an opening hole 11 which is formed at the central part of a magnetic yoke 10 which is integrally coupled with at least substantial two outside magnetic yokes of the yokes 14, 23, and 14, is also used as a fitting 12, and can magnetically insulate backs 25 of the permanent magnets 21 and 22.
