PROBLEM TO BE SOLVED: To suggest information contained in a two-dimensional code and make it familiar. A two-dimensional code 1A separates a bit string corresponding to target data from a data unit 2A and a data unit 2A, which represent a pattern in which white or black cells, which are structural units of symbols, are arranged in a matrix. One or more finder patterns include at least one specific pattern, and the data unit 2A encodes information associated with the specific pattern. Is. [Selection diagram] Fig. 3
