This invention discloses a blood component separator which comprises at least three laminated sheet-like members, blood circulation circuits laminated in at least two layers between these sheet-like members, filters for separating blood components and assembled in these blood flow paths, a plurality of connection ports disposed in the sheet-like members so as to communicate with the blood circulation circuits, a communication tube disposed in such a manner as to allow part of the connection ports to communicate with one another and to control the flow of fluid in the blood circulation circuits, and an external function part connected to the other connection ports. In this invention, the blood circuits are laminated three-dimensionally. Accordingly, more complicated blood circuits than the conventional separators where the blood circuits are integrated only two-dimensionally or on one plane can be integrated. |
