High-voltage power supply

filter circuit connected to the high-voltage generation circuit;

• an output resistor connected to the filter circuit via a first connection conductor;
• an output terminal connected to the output resistor via a second connection conductor;
• and
• a spatial noise blocking conductor connected to the first connection conductor, and having at least a portion disposed between the high-voltage generation circuit and the second connection conductor.
