PROBLEM TO BE SOLVED: To provide a game machine in which an electronic component can be mounted in an appropriate attitude.SOLUTION: A Pachinko game machine includes a game control board formed by soldering, with lead pins 769 of an electronic component inserted through through-holes 768 of a printed circuit board 755 on which prescribed wiring patterns are formed. The electronic component includes an amusement chip having contact lead pins 769b on which board contact parts are formed protrudingly in a prescribed direction. The printed circuit board 755 includes contact through-holes 768d for inserting through the contact lead pins 769b, on a ZIP (Zigzag Inline Package) mounting area 767c. Each contact through-hole 768d is so formed that first hole width W1 extending along the protrusion direction of the board contact part is set narrower than second hole width W2 extending along a direction orthogonal to the protrusion direction. |
