Abstract
A blood component collection cassette that can trap a substance where blood components coagulate by using a simple and economical configuration, and a manufacturing method of the blood component collection cassette are provided. A blood component collection cassette (28) includes a cassette main body (40) where a flow path (42) is formed and is configured to be mountable to a centrifugal separation device (14). The cassette main body (40) has a first sheet (40a) and a second sheet (40b) which are formed of a soft material. The flow path (42) is formed between the first sheet (40a) and the second sheet (40b). A filter member (60) for trapping a substance where blood components coagulate is arranged on the flow path (42) in the cassette main body (40).

A blood component collection cassette, comprising:
- a cassette main body, including a flow path, the cassette main body being mountable to a blood component separation device, wherein the cassette main body includes a first sheet formed of a soft material and a second sheet formed of the soft material and bonded to one another;
- and
- a filter member for trapping a substance where blood components coagulate in the flow path in the cassette main body,
- wherein the filter member has a cylindrically shaped filter main body,
- wherein an outer circumferential portion of the filter main body includes an annular rib, and
- wherein the first sheet and the second sheet each include a portion that conforms to the annular rib to provide a liquid-tight seal between the first and second sheets and the annular rib.
