Zusammenfassung: | A liquid discharge head includes a substrate (1) having discharge energy generating elements (2) generating energy for discharging liquid, a flow path member (17) formed over the substrate and forming a flow path for supplying the liquid, an electric wiring member (5) transmitting a signal for driving the discharge energy generating elements, and an electric connection (6) electrically connecting the substrate to the electric wiring member. The liquid discharge head has a first sealant (12) and a third sealant (11) for sealing under and over the electric connection, respectively, and a second sealant (13) for sealing side faces where no electric connection is present, the side faces being those of the substrate. An elastic modulus of the third sealant is the largest, that of the first sealant is the second, and that of the second sealant is the smallest. The first and third sealants contain the same type of resin. |
