Provides are an electrode body for measuring brain waves in which the length and direction of electrodes vary, and an apparatus for measuring brain waves using the same. According to one embodiment of the present invention, the electrode body for measuring brain waves comprises: electrodes of which one end comes in contact with the scalp and of which the length vary; and a combining body into which the electrodes are combined. Therefore, since it is possible to uniformly maintain the pressure of the electrodes applied to the scalp, a more accurate measurement of brain waves is enabled.
