A liquid container (21) has: an outer electrode (32d) contactable with an electrode (91c) of a liquid consuming apparatus; an electrode supporting member (32,33) which supports the outer electrode (32d) and is fixed to a container body (31); a piezoelectric sensor unit (35) which is discrete from the electrode supporting member (32,33), which is attached to the container body (31) for detecting liquid existing in a part of a liquid supply path and which includes a piezoelectric element (41) having an electrode (41a); and a connector (45) which has an elasticity and which electrically connects the outer electrode (32d) to the electrode (41a) of the piezoelectric element (41).
