A liquid container that, even when a local noise is generated therearound, is capable of reliably preventing error information from being written in a memory chip due to the influence of that noise is obtained. An ink cartridge 11 that is capable of writing and reading of information, from a control unit of an ink jet recording apparatus, to a memory chip 21 mounted on a container body 12 that stores liquid includes an oscillator circuit 26 that outputs a signal of prescribed frequency in response to a driving signal oscillated by a circuit on the ink jet recording apparatus side.
