A blood component collecting device (1) capable of providing high-quality, desired blood components, comprising a centrifugal separator (20) for separating blood into a plurality of blood components, a first line (21) for introducing blood into the centrifugal separator (20), a second line (22) for discharging blood components from the centrifugal separator (20), a temporarily storing bag (26') connected to the second line (22), for temporarily storing concentrated platelet plasma, a white corpuscle removing filter (261) for separating/removing while corpuscles from concentrated platelet plasma, and a platelet collecting bag (26) for storing concentrated platelet plasma that has passed through the filter (261), wherein concentrated platelet plasma in the temporarily storing bag (26') is transferred into the platelet collecting bag (26) via the filter (261), then plasma is supplied, and platelets (concentrated platelet plasma after white corpuscles are separated/removed) remaining in the filter (261) is recovered into the platelet collecting bag (26) along with plasma. |
