Ink jet recording head and apparatus having a protective member formed above energy generators for generating energy used to discharge ink
 An ink jet recording head includes energy generators for generating the energy used to discharge ink and a substrate on which a circuit electrically connected to the energy generators is formed. Also provided is a protective member on an insulating layer on the substrate above the energy generators. The area of a protective member which is in contact with the ink is made to be as small as possible.
