A method for manufacturing a liquid container to be mounted on a liquid consuming device,
  As a liquid container to which liquid should be injected,
  A liquid storage chamber capable of storing a liquid;
  A liquid supply hole connected to the liquid consumption device;
  A liquid guide path for guiding the liquid stored in the liquid storage chamber to the liquid supply hole;
  When the liquid container is attached to the liquid consuming device and the liquid stored in the liquid storage chamber is consumed, the air is discharged from the outside through the air opening hole as the liquid in the liquid storage chamber is consumed. An atmosphere communication path to be introduced into the liquid storage chamber;
  It is provided in the middle of the liquid guide path, and indicates that the liquid level of the liquid stored in the liquid storage chamber has dropped to the reference height when the air introduced from the atmosphere communication path reaches the liquid guide path. A liquid level sensor that outputs an electrical signal;
  A bubble trap channel provided in the liquid guide path between the liquid remaining amount sensor and the liquid storage chamber for capturing bubbles mixed in the liquid;
Preparing a liquid container comprising:
  Forming an inlet communicating with the atmosphere communication path by drilling; and
  Injecting a predetermined amount of liquid from the injection port;
  Sealing the inlet after completion of the step of injecting the liquid;
A method of manufacturing a liquid container to be mounted on a liquid consuming apparatus including: The method for manufacturing a liquid container according to claim 1, further comprising a step of connecting a vacuum suction means to the liquid supply hole and performing vacuum suction by the vacuum suction means. The method for manufacturing a liquid container according to claim 2, wherein the step of performing vacuum suction is performed before the step of injecting the liquid. The method for manufacturing a liquid container according to claim 2 or 3, wherein the step of performing vacuum suction and the step of injecting the liquid are performed in an overlapping manner. The said bubble trap flow path has a vertical direction conversion part which changes the direction of a liquid flow to a perpendicular direction, and a horizontal direction conversion part which changes the direction of a liquid flow to a horizontal direction. Manufacturing method of the liquid container.
