摘要：
Provided is barrier paper excellent in gas barrier properties, with respect to barrier paper including a paper substrate layer.
Barrier paper comprising a paper substrate layer, an adhesive layer, and an inorganic vapor-deposited layer in this order, the adhesive layer being in contact with the inorganic vapor-deposited layer. In the barrier paper, when the arithmetic average roughness of the surface of the inorganic vapor-deposited layer on the side opposite to the paper substrate layer is defined as Ra1, and the standard deviation of the Ra1 is defined as σRa1, σRa1 is preferably 0.030 μm or less.
