PROBLEM TO BE SOLVED: To accurately measure the residual amount of stored liquid without providing a separate chamber such as a liquid detecting chamber. SOLUTION: This liquid storage container includes: a piezoelectric detecting part mounted to a liquid lead-out part and arranged near a specific space in which liquid can exist, while applying vibration to the specific space and detecting the state of free vibration associated with the vibration; a cover member having rigidity and moving to close the specific space; and a moving member at least partially arranged in the liquid storage part and moved according to the deformation of a flexible part of the liquid storage part while moving the cover member following the movement.
