An inkjet print head includes a jet assembly which includes a nozzle plate, the nozzle plate including an ink transferring path on a bottom surface of the nozzle plate, and a jet jetting a transferred ink out of the head. A printed circuit substrate is connected to the jet assembly and includes an integrated circuit and a connection electrode. A barrier coating layer covers a surface of the printed circuit substrate and an inner surface and an outer surface of the jet assembly except a bottom surface of the nozzle plate and a surface of the connection electrode of the jet assembly and the printed circuit substrate being connected with each other. The barrier coating layer has a layered structure which includes a flexible layer, a diffusion barrier layer, and a hydrophobic layer. |
