To provide a resin base for a pinball game in which the color rendering property of a print film is good even when the print film is laminated directly.SOLUTION: A resin base (10) for a pinball game of the present invention comprises a transparent thermoplastic resin composition layer containing a first transparent thermoplastic resin (A) and a second transparent thermoplastic resin (B) different in the refraction index. The resin base (10) for the pinball game of the present invention has the thickness of 8-22 mm, and an absolute value of a difference between the refraction index (nA) of the first transparent thermoplastic resin (A) and the refraction index (nB) of the second transparent thermoplastic resin (B) is 0.01 or more. The thermoplastic resin composition layer has an overall light transmittance of 80% or less and a haze of 10% or more.SELECTED DRAWING: Figure 1 【課題】印刷フィルムを直接積層した場合にも印刷フィルムの演色性が良好な弾球遊技用樹脂基盤を提供する。【解決手段】本発明の弾球遊技用樹脂基盤（１０）は、屈折率の異なる第１の透明熱可塑性樹脂（Ａ）と第２の透明熱可塑性樹脂（Ｂ）とを含有する熱可塑性樹脂組成物層を含む。本発明の弾球遊技用樹脂基盤（１０）は、厚みが８〜２２ｍｍであり、第１の透明熱可塑性樹脂（Ａ）の屈折率（ｎＡ）と第２の透明熱可塑性樹脂（Ｂ）の屈折率（ｎＢ）との差の絶対値が０．０１以上である。熱可塑性樹脂組成物層は、全光線透過率が８０％以下かつヘイズが１０％以上である。【選択図】図１
