摘要 A liquid discharge recording head includes a recording element with a discharge port for discharging liquid and an electrically connecting portion arranged adjacent to the discharge port and receiving an electric signal for controlling the discharge of the discharge port. The liquid discharge recording head further includes a flexible wiring substrate for covering at least a portion of the recording element. The flexible wiring substrate includes each of a device hole for exposing the discharge port and a bonding hole arranged facing the electrically connecting portion independently. The liquid discharge recording head further includes a sealing agent for covering at least a portion of the electrically connecting portion and filled to at least a portion of the bonding hole. Thus, a liquid discharge recording head that enhances recording performance and that has superior productivity while maintaining reliability of the recording performance is provided.
