Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• a pressure chamber substrate including
• a first pressure chamber line having a plurality of pressure chambers arranged in a first direction, and
• a second pressure chamber line having a plurality of pressure chambers arranged in the first direction,
• the first pressure chamber line and the second pressure chamber line being provided in such a way as to be arranged in a second direction intersecting with the first direction;
• a plurality of individual electrodes individually provided to the respective pressure chambers of the first pressure chamber line and the second pressure chamber line;
• at least one common electrode provided in common to the respective pressure chambers of the first pressure chamber line and the second pressure chamber line;
• piezoelectric bodies provided between the plurality of individual electrodes and the at least one common electrode, respectively, and driven in order to apply a pressure to a liquid inside the plurality of pressure chambers;
• a first detection resistor formed from an identical material to a material of at least any of the plurality of individual electrodes and the at least one common electrode, and designed to change a resistance value depending on a temperature of the liquid inside the plurality of pressure chambers included in the first pressure chamber line;
• a second detection resistor formed from the identical material to the material of at least any of the plurality of individual electrodes and the at least one common electrode, and designed to change a resistance value depending on a temperature of the liquid inside the plurality of pressure chambers included in the second pressure chamber line;
• a wiring board;
• a first coupling terminal that couples one end of the first detection resistor and one end of the second detection resistor in common to the wiring board;
• and
• a second coupling terminal that couples another end of the first detection resistor and another end of the second detection resistor in common to the wiring board, the first detection resistor and the second detection resistor being coupled to the wiring board in parallel.
