1. A liquid ejecting head which ejects a liquid from a nozzle of a nozzle plate by means of pressure change in a pressure chamber, comprising:
a first member made of ceramics and including the pressure chamber; a second member located between the first member and the nozzle plate, the second member being made of a metal and including a first flow path at a position upstream to the pressure chamber so as to regulate an amount of liquid which flows into the pressure chamber, a third member made of ceramics, wherein the second member is between the first member and the third member; and a ground wire that grounds the second member, wherein the first flow path is at least part of a flow path which extends between a common liquid chamber from which the liquid is supplied to at least one pressure chamber and the pressure chamber, and wherein the second member includes the common liquid chamber. |
