Abstract: The present invention relates to an outer diameter measurement apparatus of an electrode assembly, which measures an outer diameter of the electrode assembly manufactured to have a cylindrical shape by winding electrodes and separators together so as to form a cylindrical shape and includes: a base plate on which the electrode assembly is mounted thereon; a guide bar configured to allow the electrode assembly to ascend from the base plate to a certain height; a housing configured to rotate around the electrode assembly ascending from the guide bar; and a sensor coupled to the housing to measure an outer diameter of the electrode assembly while the housing rotates.
