PROBLEM TO BE SOLVED: To provide a liquid jet head which has high liquid resistance, can surely make the inside of a flow channel hydrophilic, enhances bubble discharging performance, and suppresses jet failure of the liquid; a method for manufacturing the same; and a liquid jet device.SOLUTION: A liquid jet head includes a first flow channel member 15 provided with a first flow channel 18, and a second flow channel member 45 bonded to the first flow channel member 15 with an adhesive 205. On the surface of the adhesive 205 exposed in at least a portion where the first flow channel member 15 and the second flow channel member 45 are bonded to each other, a surface treatment film 210 containing a hydrophilic resin having a smaller contact angle than a contact angle of the liquid supplied to the first flow channel 18 to the adhesive 205 and a surfactant is provided.SELECTED DRAWING: Figure 4 |
