PROBLEM TO BE SOLVED: To provide a noise-reduction structure of a Pachinko machine island, which can effectively reduce noises generated in an inner space of the Pachinko machine island 10 and can be applied to existing Pachinko machine islands at low cost. SOLUTION: First sound absorbing materials 26 are arranged along the rear surfaces of top plates 12 which cover the top space S of the Pachinko machine island 10 in an openable manner. In the Pachinko machine island 10, hook pieces 27A are fixed to a rail 19 on the side of one line of Pachinko machines 17 and to a rail 19 on the side of the other line. The hook pieces 27A are bridged with the first sound absorbing materials 26. Second sound absorbing materials 30 are hung along the rear surfaces of openable/closable frieze boards 13 which constitute the front faces of the top of the Pachinko machine island 10.
