Abstract
A liquid ejecting head includes a first substrate, a nozzle plate that is laminated on the first substrate and includes nozzles configured to eject a liquid in a first direction, a second substrate that is laminated on the first substrate at a position different from the nozzle plate, a fixing plate that is laminated on the second substrate to cover the second substrate when viewed in a second direction opposite to the first direction and includes an opening portion through which the nozzle plate is exposed to an outside, and a mold that closes a gap between the nozzle plate and the fixing plate, and the opening portion has a peripheral edge that is disposed between the second substrate and the nozzle plate when viewed in the second direction.

A liquid ejecting head comprising:
- a first substrate;
- a nozzle plate that is laminated on the first substrate and includes nozzles configured to eject a liquid in a first direction;
- a second substrate that is laminated on the first substrate at a position different from the nozzle plate;
- a fixing plate that is laminated on the second substrate to cover the second substrate when viewed in a second direction opposite to the first direction and includes an opening portion through which the nozzle plate is exposed to an outside;
- and
- a mold closing a gap between the nozzle plate and the fixing plate, wherein
- the opening portion has a peripheral edge that is disposed between the second substrate and the nozzle plate when viewed in the second direction, and
- in a direction orthogonal to the first direction, an interval between the second substrate and the peripheral edge of the opening portion is longer than an interval between the nozzle plate and the peripheral edge of the opening portion.
