Provided is an engine starter having a simple structure and excellent in stability and reliability, which starts an engine while preventing an occurrence of instantaneous interruption in an electrical device mounted in a vehicle. An engine starter for driving a starter motor by closing a starter switch 5 connected in series between a power source 3 and the starter motor 2 for receiving power supply from the power source to start an engine includes: a resistor 7 connected in series to the starter switch between the power source and the starter motor, for limiting a current flowing through the starter motor; and a short-circuiting switch 6 connected in parallel to the resistor, for short-circuiting both ends of the resistor by energization of a driving coil after start of an operation of closing the starter switch, and the resistor is made of a plate-like stainless steel.
