PROBLEM TO BE SOLVED: To prevent increase of costs for manufacturing a substrate case, and to prevent illegal behaviors to a specific electronic part such as a ROM. SOLUTION: A sub control substrate 25 mounted to a slot machine being an example of a game machine is housed in a substrate case 40 for preventing the illegal behaviors. The substrate case 40 is provided with a case body part 41 and a case lid part 50 mounted to this. The case body part 41 mounts the sub control substrate 25 and has an opening part on its front side. The case lid part 50 has lid-side peripheral wall parts 52 erected at the periphery parts of a top plate part 51 arranged so as to cover the opening part. At the lid-side peripheral wall parts 52 arranged in the right and left direction of the case lid part 50, notches 43 and 44 which expose a connector arranged on the substrate are formed. In the case lid part inside of the notches, a frame 60 surrounding the ROM 26 fitted to the sub control substrate 25 projecting from the top plate part 51 and housed in the case is provided.
