The liquid receptacle () has a liquid storage chamber for storing liquid, an air flow passage connecting the liquid storage chamber to the outside air, a liquid delivery port for delivering the liquid to the liquid jetting device, an intermediate flow passage leading from the liquid storage chamber to the liquid delivery port, and a sensor disposed in the intermediate flow passage to sense whether the liquid is present or not. The liquid storage chamber includes a top storage chamber that is located at an uppermost position in the liquid storage chamber. The intermediate flow passage has a buffer chamber disposed downstream of the sensor, at a location adjacent to the top storage chamber. The liquid flow passage member () is connected to the top storage chamber, and a communication hole is formed in a wall that lies between the top storage chamber and the buffer chamber.
