摘要： A method of manufacturing a structure including a substrate and a photosensitive resin layer provided on the substrate includes irradiating a region of the photosensitive resin layer with light in a state where a layer is provided on a surface of the substrate, the region being located above a space surrounded by the substrate and the photosensitive resin layer, and the surface facing the space, and removing a portion of the photosensitive resin layer located above the space to form a hole, wherein the provided layer has a reflectance of 40% or less with respect to the light.

摘要： The present invention provides a liquid replenishment container that replenishes a liquid tank including a liquid supply portion protruding in a first direction with a liquid. The container includes: a container main body capable of storing a liquid; a liquid replenishment nozzle including a first side wall and mountable on the liquid supply portion, the first side wall defining an internal space communicating with the container main body; and a valve body provided in the internal space and causing the liquid supply portion to communicate with the internal space when the liquid replenishment nozzle is mounted. The internal space has a first liquid replenishment flow path formed between the valve body and the first side wall and being constant in cross-section in the first direction, and a second liquid replenishment flow path formed inside the first liquid replenishment flow path and being continuous in the first direction.

摘要： Provided is a method of manufacturing a liquid ejection head, which is capable of patterning a dry film while suppressing deformation of the dry film caused by a pressure. The method of manufacturing a liquid ejection head includes: preparing a substrate including an ejection orifice member on a first surface; forming, on an ejection orifice surface of the ejection orifice member, a protection film having communicating holes for allowing ejection orifices to communicate to outside; closing an opening of a supply port on a second surface on a side opposite to the first surface of the substrate with a dry film; and patterning the dry film by irradiating the dry film with light under a state in which the protection film is formed on the ejection orifice surface.

摘要： A flow path member includes a first substrate having a first surface that has a flow path, and includes a second substrate having a second surface opposing the first surface. In the flow path member in which the first and second substrates are joined together with adhesive provided between the first and second surfaces, a groove is formed in at least one of the first and second surfaces. When the first substrate is viewed from a direction orthogonal to the first surface, the flow path is disposed on a groove inner side. The groove has a first portion having a first depth and a second portion having a second depth shallower than the first depth. The second portion is that portion of the groove existing inside a region surrounded by an outer edge of the first surface and extension lines of two sides that form a flow path corner.

摘要： A flow path member includes a first substrate, a second substrate, bonding adhesive, and recessed portions. The first substrate has a first surface formed with an opening of a flow path. The second substrate has a second surface facing the first surface. The bonding adhesive bonds the first and second surfaces together. The recessed portions are formed in at least one of the first surface of the first substrate and the second surface of the second substrate. Each recessed portion is a hole configured to take up excess bonding adhesive and, as a non-through hole, does not extend through the entire thickness of a substrate. Each of the recessed portions extends into the first substrate or the second substrate as a rectangular column or an elliptical column and, when a shape of each recessed portion is viewed from the direction orthogonal to the first surface, the shape is approximately isotropic.
