PROBLEM TO BE SOLVED: To provide a circuit board having improved noise resistance.SOLUTION: The circuit board, which is used for a DC/DC converter for performing conversion between a high voltage and a low voltage and provided on the high voltage side, includes: a first switching element constituting an upper arm circuit of a first phase; a second switching element constituting a lower arm circuit of the first phase; a third switching element constituting an upper arm circuit of a second phase; a fourth switching element constituting a lower arm circuit of the second phase; a first output layer for transmitting an output current of the first phase; and a second output layer for transmitting an output current of the second phase. Each wiring that transmits a control voltage to the first to fourth switching elements is disposed in a manner not to cross over the first output layer and the second output layer of the circuit board. |
