PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine capable of quickly and accurately starting air-fuel ratio feedback during the restart of the engine of a economy running car. SOLUTION: An engine ECU performs an engine stop control when economy running engine stop conditions are established and, when the economy running engine stop conditions are established, detects an A/F lean state timeΔT if a rich signal output from an A/F sensor is not detected when an engine start control is performed, calculates a delayed time corresponding to the A/F lean state timeΔT, prohibits the A/F feedback control until a delay timer expires, and when the delay timer expires, starts the A/F feedback control.
