A particle separator for separating different types of particles with different properties includes a channel unit including a flow channel through which a first fluid having particles with at least one physical characteristic and a second fluid that flows near the first fluid, and a plurality of outflow channels that are connected to the flow channel and that separate the fluid having passed the flow channel; and a field forming unit, installed adjacent to the flow channel, for separating the particles included in the first fluid from the first fluid and generating a non-uniform field so that the particles may flow together with the second fluid.
