PROBLEM TO BE SOLVED: To provide a game machine which can be made difficult to be illegally altered or the like. SOLUTION: When an unsealing history seal 78 and a management number seal 79 as a brittle seal are stuck on a main board case 71, since the management number seal 79 is stuck over the exposed portions of the main board case 71 exposed from exposure windows 75, 75 and 75 and the peripheral portions of the exposure windows 75, 75 and 75 of the unsealing history seal 78, when the unsealing history seal 78 is illegally released, the management number seal 79 is released from the main board case 71 while being stuck on the unsealing history seal 78. At such a time, since the portion of the management number seal 79 released from the main board case 71 in contact with the main board case 71 via the exposure windows 75, 75 and 75 changes its appearance from the appearance before release, the management number seal can not be used again to make the illegal alteration or the like difficult.
