In addition, the metal vapor deposition layer 4 is of a sea/island structure so that the vapor deposition surface has insulating properties, and the metal vapor deposition layer 4 of this sea/island structure may be directly vapor-deposited to a paper base material or the vapor deposition layer 4 of the sea/island structure may be formed on a transfer film and then transferred to the paper base material. The sea/island structure of the metal vapor deposition layer 4 is preferably such that the island size is 20 nm to 1 μm and the interval between the islands is 10 nm to 500 nm. For the metal vapor deposition layer 4, aluminum, tin, zinc, a tin-aluminum alloy, a tin-silicon alloy, etc. can be used.
