Liquid ejecting head and liquid ejecting apparatus

摘要

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.

1. A liquid ejecting head comprising:
a head body configured to eject liquid; a flow path member including:
a liquid flow path for supplying the liquid to the head body;a filter that is provided in the liquid flow path to remove foreign objects in the liquid; anda detection region that has a thermal resistance lower than a thermal resistance of the remainder of the flow path member and that is provided in a part of a partition wall that partitions the liquid flow path; and a circuit substrate held by the flow path member and including a temperature detection unit configured to detect a temperature, wherein the circuit substrate is fixed to the flow path member in a state in which the temperature detection unit faces the detection region, and the detection region is provided downstream of the filter with respect to a liquid flowing direction in the liquid flow path.
