<p>A liquid droplet ejection head includes: a substrate; a nozzle plate provided on one surface of the substrate and having nozzle holes through which an ejection liquid is ejected in the form of liquid droplets; and a sealing plate provided on the other surface of the substrate, wherein an ejection liquid storage chamber which stores the ejection liquid is formed of the substrate, the nozzle plate, and the sealing plate; bonding is achieved through a bonding film at least one of between the substrate and the nozzle plate and between the substrate and the sealing plate; the bonding film contains a polyester-modified silicone material obtained by a dehydration condensation reaction between a silicone material having a branched polyorganosiloxane backbone having a structural unit represented by the following general formula (1) at a branched portion, a structural unit represented by at least one of the following general formulae (2) and (3) at a linking portion, and a structural unit represented by at least one of the following general formulae (4) and (5) at a terminal portion and a polyester resin obtained by an esterification reaction between trimethylolpropane and terephthalic acid; and the bonding at least one of between the substrate and the nozzle plate and between the substrate and the sealing plate is achieved through the bonding film due to a bonding property exhibited by the bonding film through application of energy to the bonding film:
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ R 1 -Si-X 3 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein R 1 's each independently represent a methyl group or a phenyl group; and X represents a siloxane residue.</p> |
