Abstract
An ink jet recording head and an ink jet recording apparatus using the ink jet recording head are disclosed. The adhesion between a substrate and a discharge port forming member can be improved. In order to further reduce the size of the substrate by further optimizing the arrangement of an inspection pad, at least a recording element protecting section covers the upper part of a recording element row with a conductivity, and at least an electrical circuit element protecting section covers the upper part of an electrical circuit element row with a conductivity. An inspection electrode pad is electrically connectable with the recording element protecting section and the electrical circuit element protecting section.
