ABSTRACT:
An ink jet recording head comprises an ink path communicating with an orifice for discharging an ink, and energy-generating means for generating energy to be utilized for discharging the ink from the orifice, provided along the ink path, wherein a base member provided with the energy-generating means and a resin member provided with a recess for forming the ink path are bonded to each other while keeping the recess inside, thereby forming the ink path, and wherein a shearing bonding force between the resin member and the base member is larger than a stress generated due to a difference in coefficient of thermal expansion between the resin member and the base member.
