A bioelectric signal measurement apparatus includes a first interface configured to detect a bioelectric signal of a testee through electrical interfacing with a skin of the testee a second interface configured to detect a signal different from the bioelectric signal through electrical interfacing with the skin, the second interface electrically interfacing with the skin in a state that is different from a state in which the first interface electrically interfaces with the skin and a signal processor configured to remove, from the detected bioelectric signal, a motion artifact between the first interface and the skin using the detected signal different from the bioelectric signal.
