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.

The invention is to provide a method for producing a fine structured member and a fine hollow structure, useful for producing a liquid discharge head which is inexpensive, precise and highly reliable, also to provide a method for producing a liquid discharge head utilizing such producing method for the fine structured member and the fine hollow structure and a liquid discharge head obtained by such producing method. A positive-working photosensitive material, including a ternary polymer containing an acrylate ester as a principal component, acrylic acid for thermal crosslinking and a monomer unit for expanding a sensitivity region, is used as a material for forming the Line structured member.

Method for producing fine structured member, method for producing fine hollow structured member and method for producing liquid discharge head

A method of manufacturing a liquid discharge head having an opening for discharging liquid droplets, a wall member constituting a liquid flow path to the opening, a substrate provided with and for creating a bubble in the liquid, and a movable member supported by and fixed to the substrate with the discharge opening side thereof as a free end displaced away from the substrate by pressure produced by creating the bubble to thereby direct the pressure to the discharge opening side including the steps of preparing the substrate and movable member, filling the gap between the movable member and the substrate with a liquid photo-curing resin, spin coating the resin until the resin covers the movable member, exposing an area of the resin to light to harden a portion corresponding to the wall member, and removing the unexposed portion of the photo-curing resin.
