Abstract
Such a vapor-deposited barrier film is provided that has a vapor-deposited layer having uniform film quality, a high film density and high barrier performance in the initial stage. The vapor-deposited barrier film contains a substrate having on at least one surface thereof at least one layer of a vapor-deposited layer (a). The vapor-deposited layer (a) contains a metal oxide, has a thickness of from 10 to 500 nm, and has an average value of an elemental ratio of oxygen (O) and the metal (oxygen (O)/metal) of 1.20 or more and 1.90 or less and a difference between the maximum value and the minimum value of the (oxygen (O)/metal) of 0.35 or less on analysis of the vapor-deposited layer in the depth direction thereof by an X-ray photoelectron spectroscopy (ESCA) method.
