Abstract

A recording element unit comprises an electrical connecting member (125) having a holding member (111) formed by use of an electrically insulating material and a plurality of electroconductive members (107) arranged on said holding member (111), with one end of said electroconductive member (107) being exposed on one surface of said holding member (111) and the other end of said electroconductive member (107) being exposed on the other surface of said holding member (111); and a recording element substrate having a plurality of recording elements (603) more by at least one than the necessary number arranged thereon; one end of the electroconductive member (107) exposed on one surface of said electrical connecting member (125) being connected to said recording element (603).
