Abstract

A liquid detection device (200) includes a casing main body (102) in which a passage (134) is formed and exposed in an opening (130), a sensor base (210) that is disposed to face the passage of the casing main body, a sensor chip (220) provided on the sensor base, a film (202) that seals the opening in which the sensor base is held, and a partition wall (136) that divides the passage into an upstream side (134a) and a downstream side (134b). The sensor chip has a sensor cavity (222), and the sensor base has a first hole (212) that guides a liquid from the upstream side (134a) to the sensor cavity, and a second hole (214) that guides the liquid from the sensor cavity to the downstream side (134b). The sensor base can come into contact with the casing main body through only the partition wall in a depth direction of the opening.

Description

technical field [0001] The present invention relates to a liquid detection device particularly suitable for detecting the remaining amount of liquid (ink) in a liquid consumption device such as an inkjet recording device, a liquid container including the liquid detection device, and a method of manufacturing the liquid detection device. Background technique [0002] As a representative example of a conventional liquid consumption device, there is an ink jet recording device including an ink jet recording head for image recording. As other liquid ejection devices, for example, a device having a colorant ejection head for color filter manufacture of a liquid crystal display or the like; an electrode having an electrode formation for an organic EL display or a surface emission display (FED) A device with a material (conductive paste) injection head; a device with a bioorganic substance injection head for biochip manufacturing; a device with a sample injection head as a precisi...
