PROBLEM TO BE SOLVED: To provide a game machine capable of making it difficult to manufacture a new board box from a plurality of board boxes by leaving a trace of opening of the board box. SOLUTION: The board box 201 is sealed by coupling a base-side sealing part 234 of a box base 211 with a lid-side sealing part 257 of a box lid 212 by a sealing member 260 and pouring a hardening material from a head 362 side of the sealing member 260. Since a weak projection 369 with a thin wall-thickness is formed at the head 362 of the sealing member 260, the projection 369 is broken if someone tries to open the board box 201, so that the trace of opening of the board box 201 can be left. Further, if the board box 201 is opened, the sealing member 369 is broken and the board box can not be reused, and therefore, it can be made difficult to manufacture a new board box from a plurality of board boxes.
