The biological information measurement apparatus includes a first signal applying unit which applies a first applying signal to electrodes at the time of the measurement of biological information, a biological information measurement unit which measures biological information based on detection signals of the electrodes at the time of the measurement of biological information, a second signal applying unit which applies a second applying signal to the electrodes at a time of detection of an attached state, and an attached state detection unit which detects an attached state based on the detection signals at the time of the detection of an attached state. At least some of the electrodes at the time of the measurement of biological information is identical with at least some of the electrodes at the time of the detection of an attached state.
