Claim Text:
1. A particle separation device comprising at least: a separation flow path (i) to which a separation fluid containing a particle group including two types of particles being different in density is supplied, and (ii) through which the separation fluid flows in a certain direction; a divergence section connected to at least an end of the separation flow path in the certain direction in which the separation fluid flows, a first flow path formed from the divergence section in a rising direction; a second flow path formed from the divergence section in a falling direction; a first pool for collecting the separation fluid containing the particle group which flows through the first flow path; and a second pool for collecting the separation fluid containing the particle group which flows through the second flow path, wherein the separation flow path is formed in a horizontal direction, and wherein the divergence section has a plane double-layer Y structure wherein the first flow path and the second flow path are: (i) provided in two layers, respectively; (ii) branched to form a Y shape; and (iii) parallel to a maximum surface of a chip included in the particle separation device.
