Method of manufacturing substrates with feedthrough electrodes for inkjet heads and method of manufacturing inkjet heads

摘要

A method of producing substrate 3 having feedthrough electrodes for an inkjet head, including: a step of forming grooves in the substrate 1 in the same pitch as that of the inkjet head; a step of setting conductive member 101 in the grooves; a step of adhering covering substrate 2 onto substrate 1 ; a step of cutting adhered substrate 1 and covering substrate 2 in a direction perpendicular to that of the grooves in a predetermined width.
