Abstract: A liquid consumption apparatus that detects a liquid surface level of a liquid inside a liquid container (ink tank), including: a circuit substrate; a substrate holder that holds the circuit substrate; and a control unit that detects the liquid surface level. A pair of electrically-conductive members consisting of a first electrically-conductive member and a second electrically-conductive member are provided for the liquid container. The circuit substrate is provided with a pair of terminals corresponding to the pair of electrically-conductive members. The substrate holder is provided with an elastic contact for connecting the pair of electrically-conductive members and the pair of terminals with each other. The elastic contact is a contact that is elastic in a first direction, where the first direction is a longitudinal direction of the pair of electrically-conductive members.

Abstract: A liquid ejecting apparatus includes: a container that contains a liquid having conductivity; an electrode bar that is disposed inside the container and that includes a first terminal, a second terminal, and a first insulating section that electrically insulates the first terminal from the second terminal; a detection section that detects a remaining amount of liquid contained in the container in accordance with an electrical signal from at least one of the first terminal and the second terminal; and a liquid ejection head that discharges the liquid supplied from the container. The remaining amount of liquid detected by the detection section when the first terminal is electrically coupled to the second terminal via the liquid in the container is larger than the remaining amount of liquid detected by the detection section when the first terminal is not electrically coupled to the second terminal via the liquid in the container.
