The present invention discloses a package structure of an inkjet-printhead chip. The structure includes: a nozzle structure of a print element including an ink chamber layer, a nozzle base layer on the ink chamber layer, and a nozzle layer on the nozzle base layer, wherein a plurality of nozzle through holes are set in the nozzle layer and pass through an ink chamber of the ink chamber layer; a flexible substrate set on the nozzle layer, wherein there is at least an opening set in the flexible substrate to expose those nozzle through holes; and a chip set under the ink chamber layer. Besides, the present package method is to utilize the micro-manufacturing process to form the nozzle structure of a print element and the tape automatic bonding process to bond the flexible substrate on the nozzle layer and the chip under the ink chamber layer.
