A compact and economical transcranial magnetic stimulation system is provided which allows patient to carry out transcranial magnetic stimulation therapy routinely and repeatedly in, for example, his or her house or a neighborhood primary-care medical facility. The system (1) has a magnetic field generating means for generating a magnetic field to be used for providing magnetic stimulation to a specific part of the patient's head. The magnetic field generating means has a magnetic coil (2) for generating a variable magnetic field, a holder (10) for holding the magnetic coil (2), cameras (150a) and another for recognizing respective reference markings (24) or specific portions of ears of the patient M (tragi (24)), and laser beam oscillators (160a) and another. According to the system, the coil (2) is set in a proper posture with respect to the specific part of the patient by aligning the optical axes of the cameras (150a) and other and the laser beam oscillators (160a) and other with respective tragi (24).
