Abstract
A liquid ejecting apparatus includes a liquid ejecting unit including at least one pressure chamber filled with a reactive ink, at least one nozzle communicating with the pressure chamber, a supply channel through which the reactive ink is supplied to the pressure chamber, and an elastic compliance film forming a portion of the supply channel; a piezoelectric element that changes a capacity of the pressure chamber when an electric signal is supplied to the piezoelectric element; and a flexible wiring substrate at which a signal wire for supplying the electric signal to a connection terminal of the piezoelectric element is formed. The elastic compliance film is formed of a para-aramid resin. The connection terminal and the signal wire are electrically connected to each other by solder.
