1. A blood flow measuring apparatus comprising:

  • a sensor unit including a light emitting part configured to emit light onto a measurement area and a light receiving part configured to receive the light transmitted through the measurement area;

    at least one more light receiving part configured to receive the light transmitted through the measurement area; and

    a control part configured to measure a blood flow state of the measurement area according to signals outputted by the light receiving parts,wherein the light emitted by the light emitting part is received by the light receiving parts arranged at different distances from the light emitting part and the light receiving parts output the signals responsive to the received light; and

    the control part measures the blood flow state of the measurement area by performing an arithmetic process to cancel a component of oxygen saturation in the blood, said component being included in the signals outputted by the light receiving parts.
