An ignition distributor for use in internal combustion engines has a noise preventive function capable of suppressing the generation of radiowave noises due to the spark discharge produced between a rotary electrode and stationary electrodes disposed on the side of the rotational circumference thereof opposing thereto. The ignition distributor has stationary electrodes and a rotary electrode, in which each of the plurality of stationary electrodes or rotary electrode has a main body made of a sintering product composed of powdery zinc oxide and powdery ferrite and a surface layer mainly composed of ferrite integrally formed to the surface portion of the main body.
