Abstract
An ink jet printer is provided with a driving signal generating section which generates a driving signal for driving a piezoelectric element, a residual vibration detecting section, a control IC which includes the residual vibration detecting section, and a connection terminal which connects the piezoelectric element, an input terminal to which the driving signal is supplied and an output terminal from which an output signal of the residual vibration detecting section is supplied, a first external wiring which is connected to the input terminal and through which the driving signal is supplied, and a second external wiring which is connected to the output terminal and through which the output signal of the residual vibration detecting section is supplied. A resistance value per unit length of the second external wiring is larger than a resistance value per unit length of the first external wiring.
