Provided are a particle separation device and a method of separating particles, each of which can easily separate particles for a short time without a great stress to the particles and easily collect the particles thus separated. The particle separation device includes at least: a separation flow path (i) to which a separation fluid and a particle group including two types of particles being different in density are 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; and a second flow path formed from the divergence section in a falling direction, the separation flow path being formed in a horizontal direction.
