PROBLEM TO BE SOLVED: To provide a posture control method and a posture control device for a shape-anisotropic particle capable of easily and surely measuring length, width, thickness and a surface condition of a shape-anisotropic particle such as a rice grain. SOLUTION: In the posture control method applied when the shape-anisotropic particle is arranged on a substrate and imaged by an imaging means, a guide plate having a hole for housing the particle in an erected state is arranged above the substrate of the imaging means, the particle is housed in the hole and positioned not only in a vertical direction but also in the erected state at an optional angle with respect to an imaging face. The guide plate is provided with an electrode, an electric field is applied to the electrode to attract the particle, and the guide plate is rotated or slid to position the particle not only in the vertical direction but also in the erected state at the optional angle with respect to the imaging face.
