PURPOSE: To provide a manufacturing method for high-voltage fixed resistors capable of performing trimming work easily, even when each high-voltage fixed resistor is composed of a plurality of insulating boards.
CONSTITUTION: A printed resistance board 12 is provided on an insulating board 11 by printing forming in a state of a first fixed resistor R1 containing a trimming resistor Rt and a second fixed resistor R2 being connected electrically. Next, the trimming resistor Rt of the first fixed resistor R1 is trimmed. After that, first and second insulating boards 13 and 14 having the first and second fixed resistors respectively are made by splitting the printed resistance board 12. Subsequently, the first and second fixed resistors R1 and R2 formed on first and second insulating boards 13 and 14 are connected in series electrically by the use of a connecting conductor 15.
