Abstract: Provided is a liquid container that is able to prevent or suppress spilling of a liquid that is poured into an opening part. An ink cartridge has a first wall part defining a rear end of the ink cartridge and a second wall part extending on a forward side +X from an upper edge of the first wall part. An ink inlet port that receives ink for refilling is formed in the second wall part. Ink is poured into the ink inlet port from the first wall part side. The ink inlet port has a length dimension in the front-rear direction X that is longer than in the width direction Y, and thus readily receives ink that is poured therein.
