Abstract
(EN)
Provided are magnetic particles improved in magnetism and dispersibility, and capable of maintaining a high level of magnetism. Magnetic particles according to the present invention are used to be specifically interact with a target substance. The magnetic particles each comprise: a magnetic material-containing resin particle containing a first magnetic material; a magnetic layer disposed on the outer surface of the magnetic material-containing resin particle and containing a second magnetic material; and a substance that is supported on the outer surface side of the magnetic layer and that specifically interacts with the target substance.
