To improve accuracy in checking of a coordinate measurement device by using a check gauge.SOLUTION: A check gauge 20 is a triangular pyramid-shaped check gauge for a coordinate measurement device, and includes: a plurality of support members 21 where one end is placed at a position corresponding to a vertex of the triangular pyramid and the other ends are mutually joined in an area inside the triangular pyramid; and a plurality of spheres 23 provided at positions corresponding to the vertices of the triangular pyramid in the support members 21. The shapes of at least three support members 21 among the support members 21 are mutually different.SELECTED DRAWING: Figure 3 【課題】点検ゲージを用いた座標測定装置の点検の精度を向上させることができる。【解決手段】点検ゲージ２０は、三角錐形状の座標測定装置用点検ゲージであって、一端が三角錐の頂点に対応する位置に設けられており、他端が三角錐の内側の領域で互いに結合する複数の支持部材２１と、複数の支持部材２１における三角錐の頂点に対応する位置に設けられた複数の球体２３と、を備え、複数の支持部材２１のうち少なくとも３本の支持部材２１の形状が、互いに異なる形状である。【選択図】図３
