Abstract
A plurality of pressure chamber space sections are formed at an interval therebetween on a pressure chamber substrate. The shortest distance between an opening edge of one pressure chamber space section and an opening edge of the other pressure chamber space section of adjacent pressure chamber space sections in a joining surface of a pressure chamber substrate to a communication substrate is 50 μm or more. A recess section is formed to be separated from an ink flow path in a region interposed between these opening edges. At least one of the shortest distance between the opening edge of one pressure chamber space section and the recess section and the shortest distance between the opening edge of the other pressure chamber space section and the recess section is 30 μm or less.
