Abstract
A liquid ejecting head includes a first detection resistor designed to change its resistance value depending on a temperature of the liquid inside the pressure chambers in the first pressure chamber line, a second detection resistor designed to change its resistance value depending on a temperature of the liquid inside the pressure chambers 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.
