Head unit and liquid discharging apparatus

A liquid discharging apparatus comprising:

• a creating unit that creates a driving signal;
• a first line through which the driving signal is supplied;
• a first discharging section that has a first piezoelectric element having a pair of electrodes including a first electrode, the first discharging section discharging a liquid according to displacement of the first piezoelectric element, the displacement being caused when the driving signal is supplied to the first electrode;
• a detection circuit that detects a potential of a second line;
• an inspecting section that inspects a discharging state of the liquid in the first discharging section according to a result of detection by the detection circuit;
• a first switch that makes a switchover as to whether to electrically couple the first electrode and first line together;
• a second switch that makes a switchover as to whether to electrically couple the first electrode and the second line together;
• a third switch that makes a switchover as to whether to electrically couple the first line and the second line together;
• and
• a first resistor provided in series with the third switch between the first line and the second line.
