Original Abstract Submitted

A drive circuit board includes a drive circuit that includes a first driver circuit, a first switching element pair configured to output a first switching signal, a second driver circuit, a second switching element pair configured to output a second switching signal corresponding to the first switching signal, a smoothing circuit configured to output the drive signal obtained by smoothing the second switching signal, and a bootstrap circuit that includes a first capacitor, shifts a level of a power supply voltage to be supplied to the first switching element pair, and supplies the power supply voltage to the second switching element pair, wherein a distance between the first capacitor and the first switching element pair is longer than a distance between the first capacitor and the second switching element pair.
