Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• a flow path substrate in which a plurality of nozzle flow paths, through which a liquid flows and which extend in an extending direction, are arranged in an arrangement direction intersecting the extending direction;
• and
• a nozzle substrate in which a plurality of nozzles that are directly coupled to the nozzle flow paths and that eject liquids are arranged in the arrangement direction,
• the flow path substrate and the nozzle substrate being stacked in this order from one side to another side along a stack direction intersecting the arrangement direction and the extending direction, wherein
• the flow path substrate has a protrusion portion protruding toward the other side along the stack direction,
• in one of the nozzle flow paths, the protrusion portion is continuously provided over a first position at which the protrusion portion does not overlap the nozzle when viewed in the stack direction, the first position being a position of an end portion on one side in the arrangement direction, a second position at which the protrusion portion does not overlap the nozzle when viewed in the stack direction, the second position being a position of an end portion on the other side in the arrangement direction, and a third position at which the protrusion portion overlaps the nozzle when viewed in the stack direction, the third position being a position between the first position and the second position in the arrangement direction, and
• a wall surface of the protrusion portion on one side in the extending direction at the third position is located on the one side in the extending direction with respect to a wall surface of the protrusion portion on the one side in the extending direction at the first position, and is located on the other side in the extending direction with respect to a wall surface of the protrusion portion on the one side in the extending direction at the second position.
