PROBLEM TO BE SOLVED: To provide an information carrier for antifalsification, in which an image to be observed changes in response to the angle to light source, which is excellent in judging properties of authenticity and, at the same time, is excellent in productivity. SOLUTION: This information carrier comprises specular gloss and is equipped with a first image, which is formed by changing the angle of raised printing element, and, at the same time, with a second image, which is formed by changing the difference between their printing areal percentages, so that, in the observation of an angular region, in which diffused reflected light and regular reflected light intermingle with each other, only the first image is visually recognized, while, in the observation of an observational angle region, in which diffused reflection is dominant, only the second image is visually recognized.
