PROBLEM TO BE SOLVED: To provide a stabilizing circuit of a magnet switch for a starter whose two contact points are opened to stop operation of a motor part, by preventing passage of current to a pull-in coil and a holding coil to surely reset a plunger to an original state when a key switch is turned off. SOLUTION: In the stabilizing circuit of a magnet switch for a starter, an electronic switch for the starter starting an engine mounted on a vehicle is stably operated. By using a diode passing the current in forward direction and cutting off the current in a backward direction to be in a cutoff state, the passage of current to the pull-in coil and holding coil is prevented to surely reset the plunger to the original state when the key switch is turned off, and the two contact points are opened to operate the motor part. When the diode is connected between the contact points and the pull-in coil to turn on the key switch, the pull-in coil and the holding coil are magnetized. When the key switch is turned off, the passage of current through the pulling-in coil and the holding coil is prevented not to magnetize the pull-in coil and holding coil.
