Abstract:
A liquid ejecting head includes: a piezoelectric element driven with a drive signal; a switch circuit which is provided on a circuit substrate; a pressure chamber which is filled with liquid and changes pressure inside in accordance with the drive by the piezoelectric element; and a reserve chamber which reserves the liquid to be supplied to the pressure chamber. The piezoelectric element is provided in a sealed space defined by a plurality of members including the circuit substrate. The reserve chamber includes a first flow channel and a second flow channel. A first end of the first flow channel communicates with a first end of the second flow channel. A second end of the first flow channel communicates with a second end of the second flow channel. The circuit substrate and switch circuit are provided between the first flow channel and the second flow channel.

Claim (Index 3):
The liquid ejecting head according to  claim 1 , wherein\n the liquid circulates from the first end of the first flow channel through the second end of the first flow channel, the second end of the second flow channel, and the first end of the second flow channel to the first end of the first flow channel.
