A corpuscle separation chip is presented, which is capable of separating plasma from blood using capillary forces without causing leakage of the blood in undesired directions. The corpuscle separation chip may include an upper board for securing a membrane such that one or more edges maintain non-contact, where a portion of a channel is formed in the upper board to provide a path causing plasma components separated by the membrane from blood to move in one direction; and a lower board in which another portion of the channel is formed, where the lower board is configured to join with the upper board to form the channel, and the lower board is configured to cause the plasma components to move along the channel due to capillary forces at a position corresponding to one side of a lower surface of the membrane. By using such corpuscle separation chip, each of the edges of the membrane can maintain as much non-contact as possible with the structure formed by an upper board and a lower board attached to each other, to prevent leakage of the loaded blood in undesired directions. |
