1. A liquid discharging apparatus comprising:
an accommodating container accommodating conductive liquid;
a first electrode accommodated in the accommodating container;
a second electrode accommodated in the accommodating container;
a detection portion that is electrically coupled to the first electrode and the second electrode and that detects a remaining amount of the liquid accommodated in the accommodating container in response to an electric signal from at least one of the first electrode and the second electrode; and
a liquid discharging head discharging the liquid that is supplied from the accommodating container, wherein
the first electrode includes
a first part where a distance between the first part and the second electrode is a first distance, and
a second part where a distance between the second part and the second electrode is a second distance that is longer than the first distance.
