PROBLEM TO BE SOLVED: To provide a control device for an electric variable valve timing adjusting mechanism, which provides a stable start of an engine. SOLUTION: The control device 10 for the electric variable valve timing adjusting mechanism 20 is driven by electric power supplied from the same battery 40 as a starter 30 for the internal combustion engine, and controls the electric variable valve timing adjusting mechanism 20 adjusting the opening and closing timing of an intake valve of the internal combustion engine during engine start. The electric variable valve timing adjusting mechanism 20 maintains valve timing is maintained so as to keep valve overlap period during which the intake valve and an exhaust valve overlap and open, shortest under the condition that voltage of the battery 40 gets lower than prescribed voltage at which startability of the starter 30 is deteriorated during engine start.
