Attention is paid to a relationship between the structure and characteristics of an artificial soil particle, which has so far been little studied, and a novel artificial soil particle having great potential to achieve various advantages, and a technique of producing such an artificial soil particle, are provided. An artificial soil particle (10) includes a plurality of fillers (1) having a small hole (2). The fillers bond with each other through a binder (5). The artificial soil particle (10) has a self-organized structure formed by competition between the fillers (1) and the binder (5). The self-organized structure is a three-dimensional network structure in which the fillers (1) bond with each other in a three-dimensional or a lamella structure in which the fillers (1) are aligned in a predetermined direction.
