发明名称 RECORDING APPARATUS
摘要 A liquid ejection apparatus has an ejection orifice ejecting a liquid; a liquid storage section storing the liquid; a conductive communication path forming member forming a communication path to supply the liquid from the liquid storage section to the ejection orifice; and an electrode provided inside the liquid storage section and used to detect a remaining amount of the liquid, the communication path is electrically connected to the electrode, and the electrical resistance value between the electrode and the communication path contacting the liquid when the liquid is present in the liquid storage section is smaller than the electrical resistance value between the electrode and the communication path when the liquid is not present in the liquid storage section, and a recording apparatus capable of detecting the presence or absence of ink in the recording head with high precision without increasing the size of the recording head can be provided.
