Abstract: A spherical-form measuring apparatus includes a turntable 5, a holding unit 10 for holding the sphere 20, and a probe 6 for measuring a contour of a sphere part 22 of the sphere 20. The holding unit 10 includes a base part 12, a vertical holding part 14 and an inclined holding part 16 which are placed at separate positions on the base part 12. The vertical holding part 14 holds the stem part 24 of the sphere 20 with it set in a direction perpendicular to the turntable 5. The inclined holding part 16 holds the stem part 24 with it set in a direction at an angle. The vertical and inclined holding part 14, 16 are disposed such that their axial lines meet at an intersection point P and such that the distance from the point P to the vertical holding part 14 agrees with the distance from the point P to the inclined holding part 16.
