Claim Text:
1. A liquid cartridge comprising: a liquid storing section defining a liquid storing chamber that stores liquid; a channel section defining a channel in fluid communication with the liquid storing chamber; a magnetic-field generating member provided at the channel section and configured to generate a magnetic field; a magnetic sensor provided at the channel section and facing the magnetic-field generating member with the channel interposed therebetween; a power-source terminal configured such that a power-source potential is inputted thereto, the magnetic sensor being electrically connected with the power-source terminal; a ground terminal configured such that a ground potential is inputted thereto, the magnetic sensor being electrically connected with the ground terminal; and an output terminal electrically connected with the magnetic sensor and configured to output a potential generated by the magnetic sensor, wherein the magnetic sensor is configured to generate a potential that changes depending on change of the magnetic field, the potential being higher than the ground potential regardless of the change of the magnetic field.
