An engine starting device in which an inrush current limit circuit (25), comprising a resistor (23) and a bypass relay (24) connected in parallel, is interposed between a battery (22) and a starter motor (21), and a normally open contact (26) of the bypass relay (24) is closed at the time of engine startup, wherein the engine starting device is provided with a fault identification unit (29) for identifying a fault pattern on the basis of the minimum voltage of the battery (22) while the starter motor is in operation (battery voltage minimum value A) and the amount of decrease in the voltage of the battery (22) when the normally open contact (26) is actuated in a closing direction (battery voltage recorded value B - battery voltage minimum value C).
