PROBLEM TO BE SOLVED: To provide a technology that makes it difficult to visually recognize a specific configuration of a data recording area arranged around a free area in a predetermined first state in which the data recording area is irradiated with visible light.SOLUTION: An information code 100 formed on an information code medium P has, provided inside a code area, a specific pattern area where specific patterns having a predetermined shape are arranged, a data recording area where data is recorded by a plurality of types of cells, and a free area 110 where recording of data or display of design can be performed by a method different from the method of recording data in the data recording area. The data recording area arranged around the free area 110 becomes a predetermined visual recognition difficult state in which visual recognition to specify the plurality of types of cells is difficult in a predetermined first state in which the data recording area is irradiated with visible light, and becomes a predetermined specific possible state in which the plurality of types of cells can be specified in a predetermined second state in which the data recording area is irradiated with light at a predetermined wavelength band different from that of the visible light. 【課題】可視光が照射される所定の第１状態において、空き領域の周囲に配置されるデータ記録領域の具体的構成を視認困難とすることができる技術を提供する。【解決手段】情報コード媒体Ｐに形成される情報コード１００は、コード領域の内部に、予め定められた形状の特定パターンが配置される特定パターン領域と、複数種類のセルによってデータを記録するデータ記録領域と、データ記録領域にデータを記録する方法とは異なる方法でのデータの記録又はデザインの表示が可能となる空き領域１１０と、が設けられている。そして、空き領域１１０の周囲に配置されるデータ記録領域は、可視光が照射される所定の第１状態において複数種類のセルを特定する視認が困難な所定の視認困難状態となり、可視光とは異なる所定波長帯の光が照射される所定の第２状態において複数種類のセルが特定可能な所定の特定可能状態となる構成である。【選択図】図１
