Abstract: A liquid supply apparatus includes a supply passage for supplying a liquid stored in a liquid storage section to a liquid ejection head. The liquid supply apparatus further includes: a region set within a range including an inside of the liquid storage section and an inside of the supply passage, pressure applied to the liquid in the region varying according to an amount of the liquid remaining in the liquid storage section or in the supply passage; a gas chamber communicating with the region in such a manner that a pressure of gas in the gas chamber varies according to the pressure applied to the liquid in the region; and a pressure sensor detecting pressure in the gas chamber.
