PROBLEM TO BE SOLVED: To provide a liquid containing bag capable of detecting a remaining amount of liquid, and to provide a cartridge of a liquid containing bag, and a liquid injection device. SOLUTION: The liquid containing bag 1 has a liquid supply port 4 set at a bag body 2 formed of a flexible sheet material. When a cartridge case 5 is set to a device body 12 in a state with the liquid containing bag 1 being stored in the cartridge case 5, the liquid containing bag 1 is brought in a state so that the liquid in the bag body 2 is supplied from the liquid supply port 4 to a liquid injection head 13 of the device body 12. A displacement amount of the displacement brought about to the sheet material of the bag body 2 by the consumption of the liquid is converted to a large/small value of an electrical output, whereby the remaining amount of the liquid is detected. The cartridge including the liquid containing bag 1, and the liquid injection device are also provided. Since the displacement amount of the sheet material is converted to a large/small value of the electrical output, a liquid consumption amount can be correctly grasped from the electrical output value, and also the remaining amount of the liquid is correctly displayed.
