Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ignition timing control device capable of improving fuel consumption by suitably controlling the ignition timing in idling state of an engine to secure combustion stability of the engine and perform setting to the optimum ignition timing as much as possible. SOLUTION: When the shift position is put in the range outside the neutral range or parking range, the ignition timing is set to the optimum ignition timing IGMAPN calculated according to the engine rotational frequency NE and intake pipe internal pressure PBA (S10, S15, S19). When the shift position is put in the neutral range or parking range, the ignition timing is set to the limit value IGIDLT set according to the idling target rotational frequency NOBJ and on the lag side from the optimum ignition timing IGMAPN (S15, S23 to S25).
