Abstract
A liquid ejecting head includes a head body configured to eject liquid, a flow path member including a liquid flow path for supplying the liquid to the head body, and a circuit substrate held by the flow path member and including a temperature detection unit configured to detect a temperature. The flow path member includes a detection region, which has a thermal resistance lower than a thermal resistance of other regions and which is provided in a part of a partition wall that partitions the liquid flow path. The circuit substrate is fixed to the flow path member in a state in which the temperature detection unit faces the detection region.
