PROBLEM TO BE SOLVED: To provide a game machine capable of enhancing heat radiation performance while suppressing deterioration in fitting strength of a heat generation component.SOLUTION: A base plate 43 on which an LED driver (heat generation component) 75 and LEDs 72, 73, etc. are mounted is disposed between a first member and a second member. In the base plate 43, the LED driver 75 is disposed on a first surface side opposed to the first member, and the LEDs 72, 73, etc. are disposed on a second surface side opposed to the second member respectively. A distance between the second member and the base plate 43 is made greater than a distance between the first member and the base plate 43. In the LED driver 75, a conductor part 151 on the reverse surface side is bonded to a solid ground pattern (copper foil part) 136 on the first surface side. On the base plate 43, a predetermined number of through holes 140a in which copper foil is applied to the inner surface are provided in a region corresponding to the conductor part 151 of the LED driver 75. The plate thickness of the base plate 43, and the diameter and the predetermined number of the through holes 140a are set so that the surface area of the internal surface of the through hole 140a is greater than a hole area of the through hole 140a.SELECTED DRAWING: Figure 8
