New photoelectric JHKLM observations were obtained for the star V1016 Ori. Infrared variability of the system was detected. UBVRIJHKLM observations are used to analyze the brightness of V1016 Ori outside eclipse. Its flux is shown to consist of the following components: (1) the flux from a primary B0 V star, (2) the flux from a secondary A0 V star, (3) the flux from an infrared object (an infrared component), and (4) the flux from a dust envelope around the A0 secondary with the temperature T_d = 1600 K and the equivalent radius R_d = 30 R_solar. The magnitudes of the B0 and A0 stars corrected for interstellar reddening are V_1 = (6.03 +/- 0.05) mag and V_2 = (8.4 +/- 0.2) mag, respectively. The effective temperature and bolometric luminosity of the infrared component were estimated to be T ~ 3000 K and L_3 = 150 L_solar. The infrared component may be in the Hayashi stage.
