PROBLEM TO BE SOLVED: To provide a separation detection medium capable of detecting that, adhered surfaces are separated from each other.SOLUTION: A first substrate piece 1a and a second substrate piece 1b are laminated, and adhered by adhesive coating parts 2a formed at plural positions, so that pieces can be separated freely. Coloring ink coating parts 2b are formed between the first substrate piece 1a and the second substrate piece 1b, on positions not overlapping to the adhesive coating parts 2a, and contact inhibition parts 2c are formed between the adhesive coating parts 2a and the coloring ink coating parts 2b.SELECTED DRAWING: Figure 3 |
