Abstract
A liquid droplet ejection head includes: a substrate having first and second through-holes for reserving and supplying ejection liquid; a nozzle plate on one substrate surface and covering the first and second through-holes, a sealing plate on the other substrate surface and covering the first through-holes; a driver driving the liquid droplet ejection head to eject the ejection liquid from the nozzle plate; a first bonded portion bonding the substrate to the nozzle plate; and a second bonded portion bonding the substrate to the sealing plate, the first and/or second bonded portion including a bonding film formed by drying a liquid coating formed of a liquid containing a silicone material composed of silicone compounds, and the bonding film bonding the substrate to the nozzle plate and/or the sealing plate due to a bonding property developed in the bonding film by applying energy thereto.
