A residual gas volume measuring device to accurately measuring volume of residual gas while preventing deterioration in a pump that pressurizes an airtight container. This device includes a second pipethrough which an airtight container filled with a basic carbon dioxide absorbing liquid and a second reservoir retaining pressurization water in communication with each other, a section closer to the airtight container filled with the carbon dioxide absorbing liquid, and a section closer to the second reservoir which is filled with the pressurization water; and a pump provided in the section of the second pipe filled with pressurization water. Before residual gas is introduced into the airtight container, the pump sends the pressurization water in the second pipe toward the second reservoir, and after the residual gas is introduced into the airtight container, the pump sends the pressurization water in the second pipe toward the airtight container.
