Abstract
A liquid ejection head of the present disclosure includes: a nozzle flow path including a nozzle for ejecting a liquid; and an individual supply flow path for supplying the liquid, the individual supply flow path being orthogonally connected to the nozzle flow path at an end portion of the nozzle flow path in a longitudinal direction, in which the nozzle flow path includes, at the end portion, a wall in a direction in which the individual supply flow path is connected, and the wall has an inclination.
Claims12
A liquid ejection head comprising:
- a nozzle flow path comprising a nozzle for ejecting a liquid;
- and
- an individual supply flow path for supplying the liquid, the individual supply flow path being orthogonally connected to the nozzle flow path at an end portion of the nozzle flow path in a longitudinal direction, wherein
- the nozzle flow path comprises, at the end portion, a wall in a direction in which the individual supply flow path is connected, and the wall has an inclination, and
- a connecting portion between the nozzle flow path and the individual supply flow path has a width W1 of an opening, the inclination of the wall in the direction of the individual supply flow path has a width S1 in the longitudinal direction of the nozzle flow path, and a part of the width W1 and a part of the width S1 overlap each other.
