A drive circuit which drives a capacitive load on the basis of a drive signal output from a node includes a first wire; a second wire; an amplification unit; a capacitor and a resistance element; a determination unit which determines whether or not a voltage of a differentiated drive signal is within a predetermined range in case where a magnitude of a voltage change of the signal is less than or equal to a threshold; and a voltage output unit which amplifies the a voltage of the signal by a predetermined multiple, for example, one time, and outputs the amplified signal toward the node in a case where it is determined that the voltage of the differentiated drive signal is within the predetermined range.
