PROBLEM TO BE SOLVED: To provide a method capable of accurately measuring each force component acting on a model, by providing arbitrariness in the position of sensor so as to strictly exclude the effects of inertial force that originate in vibration from a force measurement system, to flexibly cope with constitutions of various measurement systems, and also to provide a device implementing the same, in multi-component force measurement by combining a force detection sensor and an acceleration sensor. SOLUTION: The force measurement method using a force detector detecting the force in a prescribed direction acting on the measurement object via a connection member fixed to the object and the acceleration sensor fixed to the connection member or the measurement object, calculates a correlation time, in which an autocorrelation coefficient of time series signals of the acceleration sensor and the force detector is at the maximum value; detects the time when the acceleration detected by the acceleration sensor is at preset acceleration to specify the time when the time at which the autocorrelation coefficient is the maximum value has elapsed from the detection time; and adopts the detection value of the force detector in a prescribed direction at the specified time, as the value at which the inertial force due to the vibration acting on the measurement object does not affect the force detector.
