A liquid chamber for a liquid ejecting apparatus includes a prism disposed on a bottom portion of the liquid chamber. The prism includes a first reflection surface having a first reflection region by which light incident on the prism from a light emitting element is reflected when liquid does not make contact with the first reflecting region. The prism includes a relief that includes a first relief surface opposed to the first reflection region. The thickness of the prism between the first reflection region and the first relief surface is substantially constant. The constant thickness of the prism between the first reflection region and the first relief surface suppresses deflection of the first reflection region, thereby improving sensitivity for the detection of liquid in the liquid chamber. |
