PROBLEM TO BE SOLVED: To provide a game machine in which opening of a substrate case may be easily determined even in a case where a seal pasted on the substrate case is detached and then pasted again.SOLUTION: A seal 400 for sealing a base member 201 and a cover member 202 constituting a substrate case 200 capable of storing a game control board 40 comprises: first solvent use indicating parts 450A to 450D indicating a sign that a solvent A had been used when the solvent A is used; and second solvent use indicating parts 460A to 460D indicating a sign that a solvent B had been used when the solvent B is used. The first solvent use indicating parts 450A to 450D and the second solvent use indicating parts 460A to 460D are printed at positions where they do not overlap with corner parts C1 and C2 of the substrate case 200 when the seal 400 is pasted on the substrate case 200. The seal 400 also comprises a seal substrate 401 showing a color (for example, blue) different from a color (for example, red) which is shown by aging.SELECTED DRAWING: Figure 15 |
