PROBLEM TO BE SOLVED: To enable the fitting/removing of both reference electrode and earphone by single motion, and prevent the structure from being removed even when a small external pressure is applied by forming the reference electrode and the earphone into an integrated structure in an electroencephalograph having the reference electrode and the earphone. SOLUTION: An ear lobe electrode 1 and an earphone 2 are formed into an integrated structure. The adjustment of a positional relationship between the electrode 1 and the earphone 2 can be performed by a slit 4, and after the adjustment, the position is fixed with a fixing screw 3. By this constitution, the fitting/removing of both of the reference electrode 1 and the earphone 2 becomes possible. Then, the integrated structure is supported at two locations of an ear lobe and an ear hole, and the structure is prevented from easily being removed even when a small external pressure is applied. Also, a distance between the ear lobe and the ear hole differs for each person, and by fixing the structure after adjusting it in response to the distance of each person, the measurement of an electroencephalography, the transmission of a measurement result, and the stability for the attaching to the ear can be improved. |
