Abstract:
There is provided a printing head which improves durability and increases reliability by reducing stress occurring in a bonding part between an electrode pad and an inner lead at cooling. The electrode pad and the inner lead are electrically connected in such a manner that in the bonding portions between the electrode pad and a stud bump, only a part of contacting portions between the electrode and the stud bump is bonded.
