A liquid discharging apparatus has: a head unit that discharges a liquid; and a control unit that controls the operation of the head unit. The head unit has: a driving circuit board that includes a driving signal output circuit that outputs a driving signal, and also includes a substrate on which the driving signal output circuit is mounted; a discharge head that includes a driving element driven by the driving signal, a switching circuit that selectively supplies the driving signal to the driving element, and a nozzle plate in which a nozzle is formed, the nozzle discharging the liquid by being driven by the driving element; a first flow path member through which the liquid to be discharged from the nozzle passes; and a first heat dissipating member coupled to the driving circuit board. The first heat dissipating member is coupled to the first flow path member.
