Liquid ejecting head unit and liquid ejecting apparatus

A liquid ejecting head unit, comprising:

• a plurality of first nozzle flow passages extending in an X direction, liquid flowing therethrough in the X direction;
• a plurality of first nozzles arranged in a Y direction intersecting with the X direction, each of the plurality of first nozzles being continuous from corresponding one of the plurality of first nozzle flow passages, the liquid flowing through the first nozzle flow passage in the X direction being ejected from the first nozzle in a Z direction intersecting with the X direction and with the Y direction;
• a plurality of second nozzle flow passages extending in the X direction, liquid flowing therethrough in the X direction;
• and
• a plurality of second nozzles arranged in the Y direction, each of the plurality of second nozzles being continuous from corresponding one of the plurality of second nozzle flow passages, the liquid flowing through the second nozzle flow passage in the X direction being ejected from the second nozzle in the Z direction, wherein
• the first nozzle includes a first portion and a second portion, the second portion being located closer to the first nozzle flow passage in the Z direction than the first portion is,
• the second nozzle includes a third portion and a fourth portion, the fourth portion being located closer to the second nozzle flow passage in the Z direction than the third portion is,
• capacity of the first portion is smaller than capacity of the second portion,
• capacity of the third portion is smaller than capacity of the fourth portion,
• the capacity of the first portion is smaller than the capacity of the third portion, and
• a length of the second portion in the X direction is greater than a length of the fourth portion in the X direction.
