PROBLEM TO BE SOLVED: To provide a board case for a game machine capable of effectively preventing fraudulent opening of the board case in which a control board of the game machine is stored and controlling the damage from the fraudulence as much as possible by immediately discovering the fact of the fraudulent opening. SOLUTION: A case lid 300 and a case base body 200 are undetachably engaged with each other to store a control board MCB via a connection member 400 consisting of a square-pipe-shaped square pipe part and a rectangular parallelepiped wide part. The holding area of a holding means 210 disposed in the case base body is extended long to the rear of the case by holding the wide part of the connection member to a side wall of the case base body in such a way that the longitudinal direction orthogonally crosses the side wall, and therefore, the fraudulence using a drill, etc. can be effectively prevented. Even if the connection member should be destroyed and the board case is fraudulently opened, the trace of the destruction is so large that the fraudulence can be easily discovered.
