A liquid container includes: a container body which has a liquid containing portion for containing liquid therein and which is detachably mounted in a container mounting portion of a liquid consuming apparatus; a remaining liquid amount detecting unit in which a sensor member for detecting a state of a remaining liquid amount is provided in a unit case and which is detachably attached to the container body; a circuit board which has a memory device and a contact point for connecting the memory device to a connection terminal of the container mounting portion and which is attached to the container body; and a relay terminal which is attached to the unit case so as to electrically connect the sensor member to the circuit board. The remaining liquid amount detecting unit is attached to an attachment portion, which is provided at a position spaced apart from the circuit board on the container body, by a predetermined operation. The relay terminal is fixed to the unit case in a state where one end thereof comes in contact with and is electrically connected to a terminal of the sensor member, and the other end of the relay terminal is movably held on the unit case. A position regulating member for causing a position of the other end of the relay terminal to match a position of the contact point on the circuit board is provided near an attachment position of the circuit board so as to protrude from the attachment position.
