Abstract:
An ink tank capable of optically detecting ink remaining in an ink accommodation chamber with high precision is provided. A printing apparatus, a method of manufacturing the ink tank, and a method of detecting ink remaining in the ink tank are also provided. Radiated light (11) projected into an ink accommodation chamber (5A) excites an illuminant material (10) contained in ink in the ink accommodation chamber (5A) to illuminate. Based on light (12) produced by the illuminant material (10), the amount of ink remaining in the ink accommodation chamber (5A) is detected.
