Claim:
1. A cell separation container that separates a cell from a tissue using a treatment liquid, the cell separation container comprising: a collection chamber for collecting at least one of the treatment liquid and the cell; a tissue holding chamber disposed above the collection chamber and including a pouring inlet through which the treatment liquid is poured; a disc-shaped filter disposed as the entirety or part of a structure for partitioning the collection chamber and the tissue holding chamber from each other, the filter being capable of holding the tissue and allowing the cell to pass therethrough; and an air pressure adjusting mechanism capable of switching between a process of holding a treatment liquid poured into the tissue holding chamber without causing the treatment liquid to pass through the filter and a process of ejecting a treatment liquid poured into the tissue holding chamber to the collection chamber by causing the treatment liquid to pass through the filter, the switching being achieved by adjusting inflow and outflow of gases in the collection chamber and the tissue holding chamber, wherein the tissue holding chamber and the collection chamber are configured such that the treatment liquid poured into the tissue holding chamber serves as a lid that hermetically seals the collection chamber, resulting, in the gas in the collection chamber being held in the collection chamber without causing volume change.
