Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• a pressure chamber substrate that includes a plurality of pressure generation chambers;
• a nozzle plate that includes a plurality of nozzle openings;
• and
• a plurality of communication paths connecting the respective pressure generation chambers and the respective nozzle openings and have oblique portions with section areas changing from inlets on a side of the pressure generation chambers toward outlets on a side of the nozzle openings,
• wherein the oblique portions are arranged in the communication paths on the side of the pressure generation chambers or the side of the nozzle openings in a third direction such that the oblique portions are between the pressure chambers and the nozzle openings in a direction of liquid flow in the communication paths,
• wherein the plurality of pressure generation chambers are aligned in a first direction and include a first pressure generation chamber and a second pressure generation chamber that are adjacent to each other in the first direction,
• wherein the first pressure generation chamber communicates with a first nozzle opening from among the nozzle openings via a first communication path from among the plurality of communication paths,
• wherein the second pressure generation chamber communicates with a second nozzle opening from among the nozzle openings via a second communication path from among the plurality of communication paths,
• wherein the first communication path includes, on one side of a second direction, a first oblique portion with a section area changing from a side of the first pressure generation chamber toward the first nozzle opening,
• wherein the second communication path includes, on the other side of the second direction, a second oblique portion with a section area changing from a side of the second pressure generation chamber toward the second nozzle opening,
• wherein the first direction is orthogonal to the second direction on the nozzle plate,
• wherein the third direction is a direction orthogonal to both the first direction and the second direction,
• wherein the communication paths are provided in a substrate sandwiched between the pressure chamber substrate and the nozzle plate,
• wherein the first oblique portion has a section area reduced from the side of the first pressure generation chamber toward the side of the first nozzle opening,
• wherein the second oblique portion has a section area reduced from the side of the second pressure generation chamber toward the side of the second nozzle opening,
• wherein the first communication path includes, on a downstream side of the first oblique portion, a first linear portion with a uniform section area from the side of the first pressure generation chamber toward the side of the first nozzle opening, and
• wherein the second communication path includes, on a downstream side of the second oblique portion, a second linear portion with a uniform section area from the side of the second pressure generation chamber toward the side of the second nozzle opening.
