1. A liquid ejecting apparatus, comprising:
a liquid ejecting head that includes:
a nozzle surface on which a nozzle is open;
a drive element driven such that a liquid is ejected from the nozzle, wherein the nozzle surface ejects the liquid through the nozzle;
a signal generating circuit that generates a driving waveform signal to be applied to the drive element; and
a cover that covers the signal generating circuit, wherein the cover includes a channel and a first opening;
a housing that accommodates the liquid ejecting head;
a duct in which a fluid flows, wherein the duct includes:
a first duct including a first coupling section configured to attach the first duct to the housing, a first thin tube section, and a first thick tube section, and
a second duct including a second coupling section configured to attach the second duct to the liquid ejecting head, a second thin tube section, and a second thick tube section, wherein
the duct is coupled to the channel, and
the duct and the cover enable the fluid to flow therein; and
a moving mechanism that moves the liquid ejecting head relative to the housing in a moving direction intersecting the nozzle surface, wherein the second duct slides relative to the first duct in accordance with the movement of the liquid ejecting head by the moving mechanism, wherein
the signal generating circuit is between the duct and the first opening in a depth direction orthogonal to the moving direction.
