The invention discloses a magnetic disc spring in the field of springs. The magnetic disc spring comprises upper disc springs and lower disc springs, and the upper disc springs and the lower disc springs are integrally formed in a stamping manner; through holes are formed in the center of the upper disc springs and the lower disc springs; the edges of the upper and lower ends of the upper disc springs and the lower disc springs extend toward the both sides and out of upper platforms and lower platforms; and the lower end faces of the upper platforms on the both sides of a first group of the lower disc springs are fixedly provided with S pole magnets, and the upper end faces of the lower platforms on the both sides of a second group of the lower disc springs are fixedly provided with S polemagnets. The magnetic disc spring is simple in structure and high in compression resistance.
