PROBLEM TO BE SOLVED: To provide an arrangement configuration of a wiring board which can assure strength of a game board. SOLUTION: A base element 51 is equipped with an illumination part 9 made of colored plastic formed in a hollow body and a general prize opening 10 inserted into an attachment hole formed in the base element and fixed to the base element. The wiring board 54 that is formed so as to meet the shape of the base element 51 and also lap in the outline shape of the base element is arranged to be inserted in a recess 55 formed in the rear face of the base element. Thereby, there is no wiring board 54 behind the rear face of the base element 51, and attachment holes necessary to attach the base element 51 onto a game board are limited only to an attachment hole for a guiding part 16 installed to guide game balls entering the prize opening 10 to the backside of the game board, and an attachment hole for a connector 18 installed for supplying electrical signals to the wiring board 54. Therefore the size of the attachment holes bored in the game board can be largely reduced as compared with before. COPYRIGHT: (C)2004,JPO
