PROBLEM TO BE SOLVED: To more securely prevent fraudulence against a circuit on a board by exposing the board in a game machine. SOLUTION: The game machine has a board sealing means for sealing a main board inside a board storage case 200 capable of storing the main board on which a game controlling microcomputer is mounted. The board sealing means is configured not to be opened unless a part of the board storage case 200 is destroyed. The board sealing means includes a transparent cover member 560d covering the game controlling microcomputer mounted on the main board, and a fixing means for making the cover member 560d inseparable from the game controlling microcomputer unless a part of the cover member 560d is destroyed.
