PROBLEM TO BE SOLVED: To accurately detect texture of a paper sheet, without being influenced by the temperature and humidity of the environment. SOLUTION: This paper sheet texture detecting device and paper sheet processing device is provided with a drive roller 20 and a detecting roller 21 disposed in a device body 1 for holding and feeding a bill P, a piezoelectric element 71 for measuring force transmitted from a surface of the bill P via the detecting roller 21 and detecting the texture of the bill P, a temperature sensor 81 and a humidity sensor 82 for measuring at least either the temperature or the humidity inside of the device body 1, and a CPU 93 for correcting the detection value detected by the piezoelectric element 71, by adding or subtracting the measurement value measured by the temperature sensor 81 and the humidity sensor 82 as a correction value.
