Abstract: The present invention relates to a brain stimulation device, including: an electrode unit constituted by one or more electrodes and configured to move back and forth to a head of a user to fix the electrodes onto the head of the user; an auxiliary pressing unit configured to move back and forth to the head of the user to fix the electrodes onto the head of the user; and a donut type support unit having a donut type inner side on which the electrode unit and the auxiliary pressing unit are disposed and which surrounds the head, therefore a user can conveniently wear the brain stimulation device without a complicated manipulation for closely attaching the electrodes to his/her head.
