On the other hand, when the TAB tape covers the groove, it is necessary to prevent the TAB tape from loosening such as floating. This is because the TAB surface becomes a part of the ink jet head surface, and a large slack of the TAB tape comes into contact with the paper surface of the recording apparatus, and the recording paper is soiled. A capping member that prevents the nozzles of the recording element from drying is brought into contact with the surface of the TAB tape H1300.
The dent due to the slack of the AB tape causes a cap leak and deteriorates the capping performance.

As is apparent from the above description, according to the present invention, an electric wiring tape having a device hole corresponding to the recording elements on an element substrate on which a plurality of recording elements having ejection means are mounted. Is heat-bonded to electrically connect the electric wiring tape and the recording element, and the recording element is concave (mounting portion) with respect to a surface (tape bonding surface) of the element substrate to which the wiring tape is bonded. In the recording element unit, the tape adhesion surface is made of a material having a linear expansion coefficient smaller than that of the base material of the electric wiring tape, and the recording element is not mounted adjacent to the mount portion and has a window shape. Has a concave surface (dummy mount portion) having a closed edge in the tape bonding surface by being opened at the same time, and contacts the electric wiring tape so as to cover the dummy mount portion. Since the, it is possible to obtain the bonding state of the slack without smooth electric wiring tape, there is an advantage that it is possible to perform a reliable capping without leakage.
