Original Abstract Submitted

A drive circuit board includes a first driver circuit configured to output a first drive signal, a first switching element configured to output a first switching signal, a second driver circuit configured to output a second drive signal, a second switching element configured to output a second switching signal corresponding to the first switching signal, and a smoothing circuit configured to output a drive signal obtained by smoothing the second switching signal, wherein the wiring board includes a first side and a second side located so as to be opposed to each other along a first direction, a frequency of the first drive signal is higher than a frequency of the second drive signal, and a distance between the first switching element and the first driver is shorter than a distance between the second switching element and the second driver circuit.
