PROBLEM TO BE SOLVED: To prevent a deterioration in straightness of a guide surface of a stone surface plate with a variation in the ambient temperature, in an apparatus provided with the stone surface plate and uses at least one surface of the stone surface plate as the guide surface for a moving member. SOLUTION: In a coordinate measuring machine 1 provided with the stone surface plate 24, heat insulating members 60A, 60B are provided to different side surfaces 24C, 24D perpendicular to side surfaces 24A, 24B used as the guide surfaces for the moving members 12A, 12B.
