A control apparatus of a vehicular lamp (10) includes: a reference information retaining portion (108) configured to retain reference information indicative of a positional relationship of an acceleration sensor axis, a vehicle (300) axis, and a road surface, wherein the reference information is obtained in a predetermined initialization process; a correction ratio generating portion (114) configured to, after the initialization process, calculate an acceleration ratio of an amount of change in a longitudinal acceleration to an amount of change in vertical acceleration of the vehicle (300) while traveling, and derive a correction ratio for correcting a positional relationship of the road surface and at least one of the acceleration sensor axis and the vehicle axis in the reference information, using the obtained acceleration ratio; and a control portion (104) configured to output a signal for adjusting an optical axis position of the vehicular lamp (10), using the acceleration ratio, the reference information, and the correction ratio.
