摘要：
The present invention relates to fine particles in which desired magnetic particles are enclosed, the fine particles being easy to handle, having a large surface area, being resistant to settling, being compact, and having a functional group such as a carboxyl group on the particle surface. The fine particles include at least one type of polyolefin or polyolefin copolymer and at least one type of magnetic material, are substantially spherical particles having a density of 0.9 to 1.5 g/cc and an average particle size of 0.5 μm to 1,000 μm, and have a functional group on the particle surface.
