PROBLEM TO BE SOLVED: To provide a method of manufacturing a liquid jet head capable of comparatively readily and accurately carrying out the electrical coupling of a driver IC to a piezoelectric element and improving an yield, and the liquid jet head. SOLUTION: To provide a method of manufacturing a liquid jet head capable of comparatively readily and accurately carrying out the electrical coupling of a driver IC to a piezoelectric element and improving the yield, and the liquid jet head. This method of manufacturing the liquid jet head comprises a process of forming a piezoelectric element on one face side of a channel forming substrate with a diaphragm therebetween, a process of bonding a protection substrate to the channel forming substrate at the face of the side of the piezoelectric element and mounting the driver IC on the protection substrate, and a process of determining a position of a terminal of an electrode of the piezoelectric element by referencing a first positioning mark formed on the one face of the channel forming substrate and a position of a terminal of the driver IC by referencing a second positioning mark formed on the protection substrate, and connecting the terminals of the piezoelectric element and the driver IC with each other by a wire-bonding method.
