Abstract
The present invention provides a liquid storing device which can be manufactured inexpensively, which allows various liquids such as ink to be used in a chemically stable manner, and which can stably supply a liquid by reducing channel resistance irrespective of changes in position during operation to generate a predetermined negative pressure. To achieve this object, in one preferred mode, a plurality of thin plates are disposed at predetermined intervals to form a storing portion in which predetermined capillary force is generated. Furthermore, a predetermined gap is formed between the storing portion and a liquid outlet to form a guiding portion in which capillary force is generated which is stronger than the capillary force of the storing portion.
