A flexible cable includes a portion that is covered by a solder resist and an exposed portion that is not covered by the solder resist, in which the exposed portion contains a wiring terminal and at least continues to a position closer to an outside than an opening of a wiring member insertion side of a wiring vacant portion in a state in which the wiring terminal portion is connected to an element terminal of a piezoelectric element side and in which the wiring vacant portion is filled with an electrically insulating filling material in a state of covering a joining portion between the element terminal and the wiring terminal within the wiring vacant portion, and in a state in which a protective substrate, which forms the wiring vacant portion by partitioning, and the exposed portion of the flexible cable are not in contact with one another.

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 &#x3bc;m 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 &#x3bc;m or less.
