The anti-falsification fiber is made from at least two materials, i.e. an outer layer material (1) and an inner layer material (2). The inner layer material (2) is covered with the outer layer material (1). The outer layer material (1) is of color A, and the inner layer material (2) is of color B. The color A has a distinct visual difference from the color B. Moreover, after the anti-falsification fiber is put into the paper pulp, the color of anti-falsification fiber within the paper pulp when regarded in reflected light has a distinct visual difference from the color when regarded in transmitted light.
