PROBLEM TO BE SOLVED: To provide a liquid supply device capable of suppressing unnecessary liquid flow operation in a liquid supply path for supplying liquid to a liquid jet unit, and a liquid jet device including this liquid supply device.SOLUTION: A liquid supply device includes: an ink cartridge 15 storing therein ink that contains a sedimentation component sedimenting in solvent; an ink supply tube 31 that is provided between the ink cartridge and a liquid jet head 21, and in which the ink supplied to the liquid jet head can flow; a circulation pump 40 allowing the ink to flow at least in a part of the ink supply tube by operating; a temperature detection unit 52 that can detect a temperature of at least a part of the ink in the ink supply tube; and an operation control unit 51 controlling the circulation pump to operate so as to change a flow state of the ink in the ink supply tube in proportion to the detected temperature of the ink detected by the temperature detection unit. |
