1. A liquid ejecting apparatus comprising:
an ejection portion that ejects a reactive ink;
a driving circuit that generates a driving signal to drive the ejection portion;
a heat sink that dissipates heat generated in the driving circuit due to generation of the driving signal; and
a heat conduction member that conducts the heat generated in the driving circuit to the heat sink, wherein
the heat conduction member includes
a heat conductive material with an insulating property whose state is not changed by a chemical reaction with the reactive ink, and
a reinforcing member with an insulating property whose state is not changed by a chemical reaction with the reactive ink.
