Detailed two-color (BV) photoelectric photometry of the late-type eclipsing binary AD Boo was performed in April-May 1981. The period was found to be 2.0688112 d, double what was thought previously. The light curve outside the eclipses was found to be basically flat with irregular fluctuations of approximately 0.075 mag; it is basically an Algol-type curve, with a principal minimum of 0.65 mag and a secondary minimum of 0.40 mag. The O-C diagram of the minimum epoch indicates that the period has tended to decrease. The principal minimum is found to correspond to a partial eclipse of transit type.
