A force measurement apparatus that, when an insertion member is inserted into a living body vessel, measures a force at time the insertion member contacts with living body vessel, includes a force detector that measures, from an outside of a body, a force applied from the insertion member to the living body vessel, a reference point calculating unit that calculates a time point when a force applied from the insertion member into the living body vessel is individually measured based on information about the force detected by the force detector during the insertion of the insertion member into the living body vessel, and an individual force calculating unit that individually calculates the force applied from the insertion member to the living body vessel based on information about the time point and information about the force detected by the force detector.
