Abstract:
1. A noise reduction device for a starter, the starter including: a motor that is connected to a power supply line via a motor lead line and produces torque by power supplied from a battery; and an electromagnetic switch that includes an electric contact which is connected to the power supply line via a battery-side terminal and a motor-side terminal, and opens and closes the electric contact in conjunction with on-off operation of a solenoid, the noise reduction device comprising: a positive electrode that is connected to the power supply line via a branch wire; a grounding electrode that is connected to ground via a motor body of the motor; two capacitors that are connected in parallel with each other between the positive electrode and the grounding electrode; and a package into which the positive electrode and the grounding electrode are inserted and fixed, the package holding the two capacitors, wherein: the two capacitors include a capacitor body and two lead terminals that are extracted from the capacitor body in the same direction with respect to the capacitor body; the two capacitors are arranged in such a direction that the two lead terminals of one of the two capacitors face the two lead terminals of the other of the two capacitors across the positive electrode and the grounding electrode; and the two lead terminals are joined to the positive electrode and the grounding electrode by welding.
