Abstract: A particle separation chip that separates particles contained in a specimen based on particle size may include a substrate comprising a micro flow path inside of the substrate; and a perforated sheet comprising holes. The micro flow path includes: a main flow path including an inlet arranged at upstream side, into which a specimen comprising a first particle, and a second particle that is smaller than the first particle is supplied; and a first outlet arranged at downstream side, from which a specimen comprising the first particle is discharged; and a branch flow path connected to the main flow path at branches along a flow direction of the main flow path, including a second outlet from which a specimen comprising the second particle is discharged at the downstream side. The main flow path and the branch flow path are connected via the holes of the perforated sheet at the branches.
