PROBLEM TO BE SOLVED: To provide a pachinko game machine capable of easily ensuring a mounting space of a substrate box, and stably and easily mounting the same. SOLUTION: An opened window 202 is formed on a mechanism board so that a rear part of a component attached to a game board can be penetrated therethrough, a horizontal projection plate 310 is laterally placed so that it is backwardly projected with respect to the opened window 202, and a main substrate box 350 including a main substrate is mounted vertically and in parallel by the horizontal projection plate 310 and an L-shaped projection plate 322 mounted at a lower portion of the mechanism board, whereby the mounting space of the main substrate box 350 can be ensured, and the main substrate box can be stably and easily mounted. As the horizontal projection plate 310 is placed so that it is backwardly projected, the backward projection of a component to be mounted on the game board is not restricted to the utmost.
