1. An electrostatic precipitator comprising:
a charging unit having a discharge electrode that includes a plurality of electrically conductive fibers and provided to generate and diffuse ions by a discharge, a power feeding member provided to feed a high voltage to the plurality of electrically conductive fibers and a caulking part protruding toward an upstream side of a processing airflow from the power feeding member and being connected to plurality of electrically conductive fibers;
a ground electrode, at a ground potential, to attract the ions generated and diffused by the discharge electrode to charge suspended fine particles in the processing airflow by the ions, the ground electrode being among a plurality of ground electrodes and the discharge electrode being between the plurality of ground electrodes in the processing airflow; and
a dust collecting unit to collect the suspended fine particles charged by the charging unit,
wherein the plurality of electrically conductive fibers of the discharge electrode is along a downstream side of the processing airflow further than an end portion of the ground electrode along the upstream side of the processing airflow,
wherein a rear end of the plurality of electrically conductive fibers of the discharge electrode is caulked to the caulking part, and
wherein a front end of the plurality of electrically conductive fibers of the discharge electrode is spread out in a brush shape and faces the upstream side of the processing airflow.
