| 摘要 |
The present invention relates to a filter for filtering a blood sample containing a blood cell component, which comprises a main body which defines a channel for causing the blood sample to flow, an opening for introducing the blood sample, the opening being located at one end of the channel, and an opening for discharging the blood sample filtered through the channel, the opening being located at the other end of the channel. A plurality of structures are disposed in the channel to prevent the blood cell component from passing through the channel. The structures are disposed at intervals such that a slit through which the blood cell component cannot pass is formed between each structure and an adjacent inner wall of the channel and between adjacent structures. The plurality of structures and the inner wall of the channel define at least one cavity functioning as a blood cell reservoir for accommodating the blood cell component in the channel.
