PROBLEM TO BE SOLVED: To provide a DC high voltage power supply device capable of easily corresponding to a change in an output voltage and reducing manufacturing cost by improving assembly workability. ! SOLUTION: Electric circuit boards 500 each mounting a voltage doubler rectifier circuit for one step and having the same shape are stacked by the number of sheets corresponding to a desired output voltage to configure a booster circuit unit 5. A direction of the electric circuit board 500 is inverted in each step so that input terminals 503-501 of a succeeding electric circuit board 500 are located just above output terminals 504-506 of the electric circuit board 500 of a certain step and the output terminals 504-506 of the certain step are connected to the input terminals 503-501 of the succeeding step by using conductive support members 530. Further, a lamination layer structure is formed by using insulating support members 531 arranged so as to be shifted in each step to extend a creepage distance and |
