1. A gas-liquid separator for receiving a gas-containing liquid having a gas mixed therein and for separating such gas from a liquid, the gas-liquid separator comprising:
a gas-liquid separation chamber,
an inlet for depositing a gas-containing liquid into said separation chamber,
a liquid extracting member for passing liquid therethrough but restricting gas from passing therethrough, and
a gas extracting member for allowing gas to pass therethrough but restricting liquid from passing therethrough,
wherein such liquid has a surface tension characteristic and a maximum bubble growth diameter in a gravity direction which corresponds to such surface tension characteristic, and a height of the gas-liquid separation chamber is not more than such maximum bubble growth diameter and
at least one of the gas extracting member and the liquid extracting member has a reinforcing porous plate in close contact therewith.
