PROBLEM TO BE SOLVED: To provide a serial circuit device capable of securing a creepage distance required between circuit element terminals, further, reducing a limitation in component layout of an entire circuit and improving a mounting density of circuit elements.SOLUTION: A serial circuit device 2 comprises a serial circuit 10 including: a positive-side contact 3a connected to positive-side wiring connected to a positive electrode of a DC power source; a negative-side contact 4a connected to negative-side wiring connected to a negative electrode of the DC power source; a wiring pattern 8 formed between the positive-side contact 3a and the negative-side contact 4a; and a plurality of circuit elements 9, the serial circuit 10 being formed by connecting the plurality of circuit elements 9 via the wiring pattern 8 serially to each other. In the serial circuit 10, input terminals In and output terminals Out of the plurality of circuit elements are disposed while being aligned in the same direction, and the plurality of circuit elements 9 are disposed side by side in a direction crossing the direction of connecting the input terminals In and the output terminals Out. |
