Abstract
Ink is smoothly supplied so as to increase ink ejection speed to achieve high-speed printing. Thus, a filter is used to partition an ink storing chamber into a first and second storing chambers. Ink stored in the first storing chamber is supplied to a common liquid chamber in an ejection element. Ink introduced into the second ink storing chamber through a joint is supplied to the first storing chamber through the filter. An ink storing chamber member is joined to an ink storing chamber cover member to form the first and second ink storing chambers partitioned by the filter.
