Abstract
The volume measuring device has a coating forming means which, using resin, forms a coating on either part or all of the inner surface of the cylinder; a pressure measuring means which introduces a fixed quantity of gas into the cylinder in which the coating has been formed, or derives a fixed quantity of gas from the inside of the cylinder, and measures the pressure within the cylinder before and after the introduction/derivation; and a volume calculating means which uses the pressure value obtained by the pressure measuring means to calculate the volume of the cylinder.
