<p>A component separation member comprising a main body (44) inserted into a cylindrical container (42); and at least one liquid-impermeable ring-like elastic member disposed at an upper outer peripheral portion of the main body (44) and pressed against the inner wall of the container (42). This component separation member provides reliable sealability at an arbitrary position of a blood collecting tube even if it is tapered, prevents one component from mixing with the other, and allows these components to be kept in a completely separate state.</p> |
