摘要： A recording head has a channel forming member and an element substrate. A discharge port through which liquid is discharged is formed in the channel forming member. An energy generating element for discharging the liquid is formed in the substrate. A gap forming member is arranged above the channel forming member. A moisture retention liquid retention portion which retains moisture in the vicinity of the discharge port is formed between the gap forming member and the channel forming member so as to be opened toward the discharge port side. Even if the state in which the liquid is not discharged continues, the liquid in the discharge port can be prevented from drying with the recording head having the above configuration.

摘要： An ink jet recording head includes a recording element base plate having an ink heating portion for heating ink, and ink discharge ports for discharging ink heated by the ink heating portion; a main body portion having an ink supply path for inducing ink from an ink retaining portion; and a connecting member having a first bonding surface bonded to the main body portion, and a second bonding surface bonded to the recording element base plate. For this head, the connecting member is formed by material having a weaker stretching strength than that of the recording element base plate. With the structure thus arranged, it is possible to provide an ink jet recording head capable of printing high-quality images at all times without deforming the recording element base plate due to the difference in the bonding temperature of the recording element base plate and room temperature, or due to temperature changes at the time of driving, even if the number of nozzles increases and the recording element base plate is made longer.
