Abstract
A filter member including filter plates laminated in a first direction and having filter holes is included. The filter member includes a first filter plate at which a first through-hole is formed and a second filter plate at which a second through-hole is formed. The filter hole includes a penetrating portion that is a portion where a part of the first through-hole overlaps with a part of the second through-hole when viewed in the first direction and that penetrates from a first surface to a second surface, and a first portion adjacent to the penetrating portion and recessed by more than half a thickness of the filter member from a second surface to a first surface when viewed in the first direction.
Claims19
A liquid ejecting head comprising:
- a nozzle configured to eject a liquid;
- and
- a filter member that includes filter plates laminated in a first direction and that has filter holes through which a liquid supplied to the nozzle passes, wherein
- the filter member includes a first surface and a second surface facing opposite directions with respect to the first direction,
- the filter plates include a first filter plate at which a first through-hole is formed and defining the first surface, and a second filter plate at which a second through-hole is formed and defining the second surface, and
- the filter hole includes a penetrating portion that is a portion where a part of the first through-hole overlaps with a part of the second through-hole when viewed in the first direction, and that penetrates from the first surface to the second surface, and a first portion adjacent to the penetrating portion and recessed by more than half a thickness of the filter member from the second surface to the first surface when viewed in the first direction.
A liquid ejecting apparatus comprising:
- a liquid ejecting head having a nozzle that ejects a liquid;
- and
- a filter member that includes filter plates laminated in a first direction and that has filter holes through which a liquid supplied to the liquid ejecting head passes, wherein
- the filter member includes a first surface and a second surface facing opposite directions with respect to the first direction,
- the filter plates include a first filter plate at which a first through-hole is formed and defining the first surface, and a second filter plate at which a second through-hole is formed and defining the second surface, and
- the filter hole includes a penetrating portion that is a portion where a part of the first through-hole overlaps with a part of the second through-hole when viewed in the first direction, and that penetrates from the first surface to the second surface, and a first portion adjacent to the penetrating portion and recessed by more than half a thickness of the filter member from the second surface to the first surface when viewed in the first direction.
