A drive circuit capable of inhibiting a drop of a voltage of a drive signal is provided. The drive circuit includes: a drive signal output circuit configured to output a pulse signal input to a gate terminal of a first field effect transistor driving a device; a switching circuit having a switching element that is connected between the gate terminal and the signal output terminal and configured to switch a conduction state between the gate terminal and output terminal; a delay circuit configured to delay an input of the drive signal to the gate terminal by switching a state of the switching element between an on state and an off state; and a reverse flow suppressing unit configured to suppress a reverse flow of a current from the static capacitance to the drive signal output circuit. 本发明提供能够抑制驱动信号的电压下降的驱动电路。驱动电路包括：驱动信号输出电路，其将对第一场效应晶体管的栅极端子输入的脉冲信号作为驱动信号从信号输出端子输出，其中该第一场效应晶体管驱动作为进行控制的对象的装置；具有开关元件和静电电容的开关电路，其中，上述开关元件连接于上述栅极端子与上述信号输出端子之间，切换上述栅极端子与上述信号输出端子之间的通电状态，上述静电电容将与所积存的电荷相应的电压施加至上述开关元件的信号端子；延迟电路，其将上述开关元件的状态在接
