PROBLEM TO BE SOLVED: To provide an anticounterfeit medium in which authenticity is discriminable without breaking a substrate; an anticounterfeit effect is improved by such characteristics that a composite pattern is not viewed in observation under normal diffusion reflection light and is visible in observation only under regular reflection light; and authenticity determination is improved.SOLUTION: In an anticounterfeit medium in which a foil having a metallic sheen is formed on a part of a substrate, a composite pattern expressing one significant information is formed on a part of the foil having the metallic sheen by a first pattern portion partitioned and formed by disposing a first pattern component having at least one recessed or projecting shape and a second pattern portion formed by a coloring material visible at least under regular reflection light. 【課題】基材を破壊することなく真偽判別が可能であり、通常の拡散反射光下の観察では合成模様が視認されることがなく、正反射光下のみの観察で視認可能とすることで偽造防止効果が向上し、かつ、視認性の良い合成模様によって真偽判別性が向上した偽造防止媒体を提供する。【解決手段】基材の一部に、金属光沢を有する箔が形成された偽造防止媒体において、金属光沢を有する箔の一部に、少なくとも一つの凹形状又は凸形状の第１の模様構成要素が配置されることで区分けして形成された第１の模様部と、少なくとも正反射光下で視認可能な色材によって形成された第２の模様部によって、一つの有意情報を表す合成模様を形成する。【選択図】 図１
