Disclosed is a transcranial magnetic stimulation (TMS) stimulation navigation method comprising the steps of: acquiring a stimulation target point in the brain of a subject to which an electrical stimulus is to be applied; acquiring data on the spatial distribution of a magnetic vector potential of a coil for a TMS procedure; acquiring, from the spatial distribution, at least one parameter for acquiring an optimal stimulation condition for the stimulation target point; and by using the acquired parameter, calculating a position and direction of the coil satisfying the optimal stimulation condition for the stimulation target point.
