PROBLEM TO BE SOLVED: To provide a valve control device of an internal combustion engine capable of reducing pumping loss at low rotation speed. SOLUTION: A valve control device 1 of an internal combustion engine for lifting a valve 112 via a rocker arm 201, consists of: a lift operation angle variable mechanism 100 which successively varies a lift amount and operation angle of the valve 112; and a rocker ratio variable mechanism 200 which successively varies a rocker ratio of the rocker arm 201 and which reduces the operation angle of the valve 112 as the rocker ratio is increased.
