PROBLEM TO BE SOLVED: To provide a method for calibrating an accelerometer by actually applying acceleration to the accelerometer from every direction because there are cases where accurate acceleration value cannot be obtained even if performing one-dimensional calibration as is conventionally done, because of application of every-direction acceleration to the accelerometer. SOLUTION: This measurement device includes: a vibrating table causing translation motion or rotary motion; an acceleration measurement device, an angular velocity measurement device or an angular acceleration measurement device; an output means taking out output from the device; one or more light reflectors; a displacement measurement means capturing multidimensional motion by use of a laser interferometer irradiating the light reflector with light from a plurality of directions; a data processor processing data on a motion state from the displacement measurement means to process the multidimensional translation motion or rotary motion; and a display means displaying output of the data processor and output of the acceleration measurement device, the angular velocity measurement device or the angular acceleration measurement device, or a transmission means transmitting the output.
