A method for taking out paper sheets that is capable of accurately taking out paper sheets (for example, separator cards) stored in a paper sheet storage container one-by-one at low cost. In this paper sheet taking-out method, air is blown from the side of or below the paper sheet while it is in a spread state, so that the upper surface of the paper sheet is raised. In this state, sucking the upper surface of the paper sheet by a suction mechanism allows for taking out the paper sheet with high accuracy.
