An electronic control device for an internal combustion engine which comprises: means of detecting a first crank angle position, SGTT and a second crank angle position, SGTL provided at a position on advance ignition angle side of the first crank angle position; means of calculating and setting the target ignition timing at every SGTL; means of determining a restriction time corresponding with a time interval between the SGTT and a target ignition timing when the target ignition timing is set at a timing on retarded ignition angle side of the SGTT; means of determining whether an ignition is generated after the restriction time elapses; and means of forcibly generating the ignition signal when the ignition is determined not to be generated.
