Abstract
A biological material extraction carrier includes a magnetic bead including a magnetic metal powder and a first coating layer that coats a particle surface of the magnetic metal powder and that is made of a first oxide material, and an oxide powder, in which a particle surface is made of a second oxide material, and an average particle diameter is smaller than that of the magnetic bead. Further, the average particle diameter of the magnetic bead is preferably 0.5 μm or more and 50 μm or less.
