To provide a correction parameter preparation method of an attitude detector capable of preparing inexpensively a correction parameter for correcting an error of a detected value due to an angle error in attaching a sensor, and to provide a correction parameter preparation device, and an attitude detector with correction capability.
A rotation plate 230 is disposed so that an upper surface 231 is horizontal (S10), and an attitude detector 1 is fixed to a surface 211 of a cubic tool 210 so that X axis (first axis) is perpendicular to a surface 212 (second surface), Y axis (second axis) is perpendicular to a surface 213 (third surface), and Z axis (third axis) is perpendicular to a surface 211 (first surface) (S12). Then the surfaces facing the surfaces 212, 213 and 211 of the cubic tool are fixed in order to the upper surface of the rotation plate (S14, S20, S26), a detected value of the attitude detector is taken under motionlessness or rotation at a predetermined angular velocity of the rotation plate (S16, S18, S22, S24, S28, S30), and a correction parameter is prepared (S32).
