The present invention provides amphiphilic polymer particles which are formed from a naturally derived starting material and exhibit hydrophobicity, while maintaining an adequate water absorption. An amphiphilic alginic acid particle group which is obtained by subjecting a polyvalent metal salt of alginic acid to a hydrophobization treatment with use of a hydrophobizing agent, wherein: some metal ions in the polyvalent metal salt of alginic acid are hydrophobized through a chemical bond with the hydrophobizing agent; the contact angle at 30 seconds after dropping a water droplet on the particle group is from 300 to 150°; and the water absorption per 100 g of the particles is not less than the oil absorption per 100 g of the particles.
