Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• a flow path forming substrate that has a plurality of pressure generation chambers, the plurality of pressure generation chambers communicating with a plurality of nozzles, each of the plurality of nozzles discharging liquid;
• and
• a communication plate that has a plurality of supply paths and a manifold, the plurality of supply paths communicating between the plurality of pressure generation chambers and the manifold, part of the manifold being configured with first and second recesses, the first and second recesses being open to a side opposite to the flow path forming substrate,
• wherein the second recess is deeper than the first recess,
• wherein the plurality of supply paths penetrate a bottom of the first recess so as to form a plurality of through holes in the bottom of the first recess, and the plurality of supply paths are arranged in a first direction,
• wherein a plurality of inclined surfaces are provided between the bottom of the first recess and a bottom of the second recess in the manifold along the first direction, each of the plurality of inclined surfaces is inclined toward the bottom of the second recess from the bottom of the first recess,
• wherein the plurality of inclined surfaces are configured by a plurality of first inclined surfaces and a plurality of second inclined surfaces, the plurality of first and second inclined surfaces have different angles to each other and are alternately arranged, and
• wherein a pitch of adjacent two of the plurality of second inclined surfaces is smaller than a pitch of adjacent two of the plurality of supply paths.
