Abstract:
An inkjet print head is provided with a plurality of electrode terminals connected to a plurality of connecting terminals extending from electrical wiring members transmitting drive signals of elements generating energy for ejecting ink, and an insulating portion for insulating the extending portion of the connecting terminal to the connecting portion where the connecting terminal is connected to the electrode terminal from the print element substrate, the connecting portion being sealed by a sealant spreading due to a capillary force between the plurality of the connecting terminals. In order to prevent occurrence of the non-existence region of the sealant due to the blocking of the sealant by the insulating portion, the insulating portion is constructed of a plurality of separated convex portions in contact with the plurality of the connecting terminals respectively to form a groove between the convex portions for allowing the passing of the sealant.
